Middle Dutch and Dutch tin, Old High German zin, German Zinn, Old Norse tin), of unknown origin, not found outside Germanic.

Other Indo-European languages often have separate words for "tin" as a raw metal and "tin plate;" e.g. French étain, fer-blanc. Pliny refers to tin as plumbum album "white lead," and for centuries it was regarded as a form of silver debased by lead. The chemical symbol Sn is from Late Latin stannum (see stannic ). Tin-type in photography is from 1864. Tin ear "lack of musical discernment" is from 1909. Tin Lizzie "early Ford, especially a Model T," first recorded 1915.

It is the general opinion that the Phoenicians of Tyre and Sidon obtained their supplies of tin from the British Isles. In Ezek.

27:12 it is said to have been brought from Tarshish, which was probably a commercial emporium supplied with commodities from other places. In Isa. 1:25 the word so rendered is generally understood of lead, the alloy with which the silver had become mixed (ver. 22). The fire of the Babylonish Captivity would be the means of purging out the idolatrous alloy that had corrupted the people. Easton's 1897 Bible Dictionary Tin - Element information, properties and uses | Periodic Table Chemistry in its element: tin (Promo) You're listening to Chemistry in its element brought to you by Chemistry World, the magazine of the Royal Society of Chemistry. (End promo) Chris Smith Hello, this week the element that changed the course of industry and also gave birth to the Bronze Age. We find out why the Romans came to Britain and why your organ can go out of tune in winter perhaps irreversibly. But tin fans should watch out because much of what we call tin isn't. Katherine Holt Tin cans, tin foil, tin whistles, tin soldiers.....these are that things that come to mind when we think of tin.

Which is unfortunate, as tin cans are actually made from steel; tin foil is made from aluminium and tin whistles....well you get the idea. To be associated with a list of obsolete consumable items is especially unfortunate for tin, when we consider that it was responsible for literally changing civilisation! Have you heard of the Bronze Age? Well, some enterprising metal workers at the end of the Stone Age discovered that the addition of a small amount of tin into molten copper resulted in a new alloy. It was harder than copper but also much easier to shape, mould and sharpen. This discovery was so revolutionary that that Bronze Age was born - a name given to any civilisation which made tools and weapons from this alloy of copper and tin. So important was tin that the secrets of its trade were closely guarded. The ancient Greeks spoke of the 'Cassiterides ' or 'Tin Islands' which were believed to lie off the north west coast of Europe. These mysterious islands have never been identified and probably never existed. All the Greeks knew was that tin came to them by sea and from the north-west and so the story arose of the tin islands. It is likely the tin came from northern Spain and from Cornwall.

In fact, the strategic importance of the Cornish tin mines is considered one of the reasons why the Roman Empire invaded Britain. Tin may have played another historical role - this time in the defeat of Napolean's army in the Russian campaign of 1812. It has been claimed that in the severe cold the tin buttons on the soldier's uniforms disintegrated into powder, leading to severe loss of life from hypothermia. The accuracy of this story is debatable, but the transformation of tin from a shiny metal into a grey powder at low temperatures is chemical fact. In the cold winters of Northern Europe the loss of tin organ pipes as they began to disintegrate into dust has been known for centuries as 'tin pest', 'tin disease' or 'tin leprosy'. This process is actually a very simple chemical transformation of one structural form of tin - silvery, metallic 'white tin' or 'beta tin' - into another - brittle, non-metallic 'grey tin' or 'alpha tin'. For pure tin the transition occurs at 13.2 oC but the transition temperature is lower, or does not occur at all, if there are enough impurities present, for example if tin is alloyed with another metal.

A modern day problem with 'tin pest' has thus arisen, as the tin-lead alloys used to coat leads in electrical equipment have sometimes been replaced with pure tin due to new environmental legislation. In cold temperatures the metallic beta tin coating transforms into non-conducting, brittle alpha tin and falls off the leads. The loose alpha tin powder then moves around inside the equipment, but because it is non-conducting it doesn't cause a problem. However, in warmer temperatures this alpha tin powder transforms back to conducting beta tin, leading to short circuits and all kinds of problems. The way to defeat 'tin pest' is to mix tin with other metals, and these days tin is mainly used to form alloys - for example bronze, pewter and solders. Since tin is the most tonally resonant of all metals it is used in bell metals and to make organ pipes, which are generally a mix of 50:50 tin and lead. The proportion of tin generally determines the pipe's tone. And so we return to the humble tin can. Although not made from tin, cans are often coated with tin on the inside to prevent corrosion.

So while it may now seem that tin plays a small role in our everyday lives, remember that once it figured in the rise and fall of civilisations. Chris Smith So it was the tin that lured the Romans to Britain - funny that, there was me thinking it was the wonderful weather. Telling Tin's tale was Katherine Holt from UCL. Next week the substance that makes you see red. Brian Clegg If you are listening to this podcast on a computer with a traditional colour monitor Europium will be enhancing your view of the Chemistry World website. When colour TVs were first developed, the red pixels were relatively weak, which meant the whole colour spectrum had to be kept muted. But a phosphor doped with europium proved a much better, brighter source of red and is still present in most surviving monitors and TVs that predate the flat screen revolution. Chris Smith And you can hear from Brian Clegg how the power of Europium was harnessed in the first place and how it was discovered on next week's Chemistry in its Element, I hope you can join us.

[Middle English, from Old English.] Word History: The origins of the word tin may date to a time before Western Europe was settled by speakers of Germanic, Celtic, and other branches of the Indo-European language family. Related words for this metal are found in almost all Germanic languages, such as German Zinn, Swedish tenn, and Old English tin (the source of the Modern English word). Together, these Germanic words suggest the reconstruction of a Proto-Germanic word *tinam, "tin," but no other branch of Indo-European language family has a word exactly comparable to this. Latin has a vaguely similar-sounding word for tin, stagnum (also spelled stannum), that may have been borrowed from a Celtic source.

These facts suggest that the Germanic word for tin may originate in a pre-Indo-European language of Western Europe. This possibility is supported by the Bronze Age importation to the Near East of tin and copper from Western Europe. There are relatively few rich deposits of tin in the earth's crust, and production of bronze in the ancient world was limited by the availability of tin. During the Bronze Age, the civilizations of the Near East and the Mediterranean area depended on relatively few sources to provide the tin needed to make bronze. The Greek historian Diodorus Siculus, writing in the 1st century bc, explains that much ancient tin came from deposits in Cornwall in Britain. From there, it was shipped through Gaul to supply the rest of the Mediterranean world. At the time when the early Indo-European peoples began to move westward from their homelands in Eastern Europe—sometime after 4000 bc—they had probably just mastered early techniques of bronze production, in which arsenic rather than tin is alloyed with copper. Tin, however, makes a much superior kind of bronze, and the early Indo-European peoples may have borrowed words for tin from local peoples who were already trading in tin ingots or working the tin deposits of Western Europe.

ھولنے کا آلہ cái mở hộp 开罐头刀 Tin Tin»the essentials [WebElements Periodic Table] Element News Tin: the essentials Ordinary tin is a silvery-white metal, is malleable, somewhat ductile, and has a highly crystalline structure.

Due to the breaking of these crystals, a "tin cry" is heard when a bar is bent. The element has two allotropic forms. On warming, grey, or α-tin, with a cubic structure, changes at 13.2°C into white, or β-tin, the ordinary form of the metal. White tin has a tetragonal structure. When tin is cooled below 13.2°C, it changes slowly from white to grey. This change is affected by impurities such as aluminium and zinc, and can be prevented by small additions of antimony or bismuth. The conversion was first noted as growths on organ pipes in European cathedrals, where it was thought to be the devils work. This conversion was also speculated to be caused microorganisms and was called "tin plague" or "tin disease". Tin resists distilled, sea, and soft tap water, but is attacked by strong acids, alkalis, and acid salts. Oxygen in solution accelerates the attack. When heated in air, tin forms SnO2. It is, or was, used to plate steel, making "tin cans". Tin is used as one component in bell metals.

Second ionisation energy : 1411.8 kJ mol‑1 Isolation Isolation : tHere is normally little need to isolate tin metal in the laboratory as it is readily available commercially. Tin is commonly available as the mineral cassiterite, SnO2. Reduction of this dioxide with burning coal results in tin metal and was probably how tin was made by the ancients. SnO2 + 2C → Sn + 2CO Read more » Tin has the most stable isotopes (10) of all elements. Tin isotopes are used in a variety of applications. Sn-112 is used as precursor in the production of the radioisotope Sn-113 while Sn124 is used for producing Sb-124. Sn-116 and Sn-117 can both be used for the production of the medical radioisotope Sn-117m which is used in treating bone cancer. Both Sn-118 and Sn-119 have been evaluated for the production of Sn-119m. Tin Appearance and Characteristics Harmful effects: Tin is considered to be non-toxic but most tin salts are toxic.

The inorganic salts are caustic but of low toxicity. Organometallic compounds of tin are highly toxic. Characteristics: Tin is a silvery-white, soft, malleable metal that can be highly polished. Tin has a highly crystalline structure and when a tin bar is bent, a ‘tin cry’ is heard, due to the breaking of these crystals. In compounds tin is usually in the divalent state (Sn2+) or tetravalent state (Sn4+). It resists oxygen and water but dissolves in acids and bases. Exposed surfaces form an oxide film. When heated in air, tin forms tin(IV) oxide (stannic oxide) which is feebly acidic. Tin has two allotropic forms at normal pressure, gray tin and white tin. Pure white tin slowly tends to become the gray powder (gray tin), a change commonly called ‘tin pest’ at temperatures below 13.2 oC. Gray tin has no metallic properties at all. Commercial quality tins are resistant to tin pest as a result of the inhibiting effects of minor impurities. Uses of Tin Tin is used as a coating on the surface of other metals to prevent corrosion.

‘Tin’ cans, for example, are made of tin-coated steel. Tin can be rolled into thin foil sheets (tinfoil). Present day ‘tinfoil’ to cover or wrap food is usually made from aluminum. Alloys of tin are commercially important in, for example, soft solder, pewter, bronze and phosphor bronze. Tin chloride (stannous chloride, SnCl2) is used as a mordant in dyeing textiles and for increasing the weight of silk. Stannous fluoride (SnF2) is used in some toothpastes. Abundance and Isotopes Abundance earth’s crust: 2.3 parts per million by weight, 0.4 parts per million by moles Abundance solar system: 9 parts per billion by weight, 0.1 parts per billion by moles Cost, pure: $24 per 100g Cost, bulk: $1.80 per 100g Source: Tin very rarely occurs free in nature. The chief ore is cassiterite (SnO2). The metal is prepared from cassiterite by reducing the ore with coal.

Isotopes: Tin has 35 isotopes whose half-lives are known, mass numbers 100 to 134. Tin has ten stable isotopes, the most of any element. Naturally occurring tin is a mixture of its ten stable isotopes and they are found in the percentages shown: 112Sn (1.0%), 114Sn (0.7%), 115Sn (0.3%), 116Sn (14.5%), 117Sn (7.7%), 118Sn (24.2%), 119Sn (8.6%), 120Sn (32.6%), 122Sn (4.6%) and 124Sn (5.8%).

A brittle form with orthorhombic structure may exist above 161&degC;.

Below 13.2&degC; pure tin tends to become a gray powder, a change commonly designated "tin pest" or "tin disease." Tin is very soft (only slightly harder than lead) and malleable; it can be rolled, pressed, or hammered into extremely thin sheets (tin foil). When iron or steel is dipped into molten tin, a layer of tin is deposited on the surface. A tin coating may also be applied by electroplating, which uses less tin. The tin serves to prevent rusting, since it is barely affected by moisture. The tin plate used in tin cans is an iron or steel sheet coated with tin. A tin coating is used to protect copper and other metals. Tin is a component of antifriction metal, bell metal, britannia metal, bronze, gunmetal, pewter, solder, and other alloys. Tin forms stannous compounds, in which it has valence +2, and stannic compounds, in which it has valence +4, as well as stannites, stannates, and other complex salts.

Industrially useful compounds of tin include stannous chloride, important as a reducing agent, as a mordant in dyeing, and for weighting silk; stannic chloride, for the last two purposes and to stabilize perfume and color in soap; stannic oxide, for the preparation of white porcelain enamelware; and sodium stannite, a reducing agent. Stannous fluoride is added to toothpastes and water supplies to prevent tooth decay. Tin forms a number of toxic organometallic compounds that are used as fungicides, catalysts, and for other uses. Tin very rarely occurs uncombined in nature; the dioxide, which occurs as cassiterite, or tinstone, is the only ore of commercial importance. It is obtained chiefly from Bolivia, Indonesia, the Malay Peninsula, Congo (Kinshasa), and Nigeria. The tin mines of Cornwall, England, were formerly the principal source. The metal is prepared from cassiterite by heating in the reverberatory furnace. The ore from the mines is first given special treatment, and the "concentrates" thus obtained are mixed with coal in the furnaces. Tin was known and used by humans at least as early as the Bronze Age.

The metal and its compounds were known and used by the alchemists. In 1673, Robert Boyle published a description of experiments on the oxidation (calcination) of tin. The metal was recognized as an element by Lavoisier. tin A lustrous white, soft, and malleable metal having a low melting point; relatively unaffected by exposure to air; used for making alloys and solder, and in coating sheet metal. See also: Metal Tin (Latin, stannum), Sn, a chemical element in group IV of the Mendeleev periodic table. Atomic number, 50; atomic weight, 118.69; a white, shiny, heavy, soft, and malleable metal. The element has ten naturally occurring isotopes: 112Sn, 114Sn, 115Sn, 116Sn, 117Sn, 118Sn, 119Sn, 120Sn, 122Sn, and 124Sn.

124Sn is slightly radioactive, and 120Sn has the largest natural distribution, with approximately 33 percent off all tin occurring in this form. Historical information. Bronze, an alloy of tin and copper, was known as early as 4000 B.C ., and pure tin was in use by 2000 B.C . Ancient civilizations fashioned ornaments, dishes, and utensils from tin. The precise origin of the words “stannum” and “tin” has not been established as yet. Occurrence in nature. Tin is a basic component of the earth’s upper crust, comprising 2.5 × 10-4 percent by weight of the lithosphere, 3 × 10-4 percent of acid igneous rocks, and 1.5 × 10-4 percent of intrusive basic rocks. The mantle contains even smaller amounts of tin. Tin deposits are associated with magmatic processes (such formations as stanniferous granites and pegmatites) and with hydrothermal processes. Of the 24 stanniferous minerals, 23 were formed under conditions of high temperature and pressure.

After cassiterite (SnO2), stannite (Cu2FFeSnS4) is today’s most commercially valuable mineral source of tin. Tin migrates poorly in the biosphere. Seawater contains only 3 × 10-7 percent tin, although certain species of seaweed exhibit a higher tin content. Nevertheless, tin does tend to diffuse throughout the biosphere. Physical and chemical properties. Two allotropic forms of tin are known: α-Sn, or gray tin, and the more common β-Sn, or white tin. Gray tin occurs below 13.2°C and has a stable cubic lattice structure similar to that of diamond and a density of 5.85 g/cm3. White tin crystals are tetragonal. with lattice indexes a = 5.813 angstroms (Å) and c = 3.176 Å; the density of white tin is 7.29 g/cm3. The transformation of white to gray tin is accompanied by pulverization.

Tin exhibits the following properties: melting point, 231.9°C; boiling point, 2270°C; thermal coefficient of linear expansion, 23 × 10-6 from 0° to 100; specific heat, 225 joules per (kg.°K) at 0°C, or 0.0536 cal per (g · °C); thermal conductivity, 65.8 watts per (m.°K) at 0°C, or 0.157 cal per (cm. sec · °C); electrical resistivity, 0.115 × 10-6 ohm · m at 20°C, or 11.5 × 10-6 ohm · cm; tensile strength, 16.6 meganewtons per sq mm, or 1.7 kilograms-force per sq mm; relative extension, 80–90 percent; Brinell hardness, 38.3–41.2 meganewtons per sq m, or 3.9–4.2 kilograms-force per sq mm.

Bars of tin produce a characteristic crackling sound, called tin cry, when bent; this is a result of friction between crystalline layers. In accordance with the electron configuration of the outer shell (5s25 p2), tin exists in the oxidation states +2 and +4, the latter being more stable. Sn (II) compounds are strong reducing agents. The formation of a thin, strong, nonporous SnO2 film on the surface of tin upon exposure to dry or humid air practically prevents oxidation at temperatures of up to 100°C. Tin remains stable in both cold and boiling water. The standard electrode potential of tin in acid medium is – 0.136 volts. Tin gradually displaces hydrogen in cold, dilute HCl and H2SO4 to form SnCl2 and SnSO4, respectively. It dissolves upon heating in hot, concentrated H2SO4 to yield Sn(SO4)2 and SO2.

Dilute nitric acid at 0°C reacts with tin according to the equation 4Sn + 10HNO3 = 4Sn(NO3)2 + NH4NO3 Tin oxidizes upon heating with concentrated HNO3 (density 1.2–1.42 g/cm3) to produce a metastannic acid residue with a variable degree of hydration: 3Sn + 4HNO3 + n H2O = 3H2SnO3 · n H2O + 4NO Hydrogen is liberated upon heating Sn in concentrated alkaline solutions, yielding hexahydrostannate: Sn + 2KOH + 4H2O = K2[Sn(OH)6] + 2H2 Atmospheric oxygen produces an SnO2 film on the surface of the metal. Stannic oxide (SnO2) is highly stable, but stannous oxide (SnO) undergoes rapid oxidation and therefore must be prepared by indirect methods. SnO2 displays predominantly acidic properties, and SnO basic properties. Tin does not combine directly with hydrogen.

For example, stannic hydride, SnH4, is formed upon interaction of Mg2Sn and hydrochloric acid: Mg2Sn + 4HCl = 2MgCl2 + SnH4 The hydride SnH4 is a colorless, poisonous gas with a boiling point of – 52°C. Extremely unstable, SnH4 decomposes into Sn and H2 within a few days at room temperature; decomposition is instantaneous at temperatures above 150°C. SnH4 is also formed during the precipitation of Sn salts in the presence of hydrogen, for example, SnCl2 + 4HCl + 3 Mg = 3MgCl2 + SnH4 Tin combines with halogens to yield compounds of the formulas SnX2 and SnX4. The former are saltlike compounds that yield Sn2+ ions in solution, while the latter (except SnF4) are both hydrolyzable and soluble in nonpolar organic liquids. The interaction of tin and dry chlorine yields stannic chloride (SnCl4), a colorless liquid that is used as a solvent for sulfur, phosphorus, and iodine.

The reaction is Sn + 2Cl2 = SnCl4 This reaction was previously employed to extract tin from defective tin-plated products. It is not widely used today, because of the chlorine toxicity and tin losses involved. Tetrahalides of the formula SnX4 produce complexes with H2O, NH3, nitrogen oxides, and PCl5, as well as with alcohols, ethers, and many other organic compounds. Hydrohalide acids combine with tin halides to yield complex acids that are stable in solution, for example, H2SnCl4 and H2SnCl6. Simple or complex chloride solutions hydrolyze upon dilution with water or upon neutralization to form white Sn(OH)2 or H2SnO3 · nH2O precipitates. The interaction of tin and sulfur yields brown stannous sulfide (SnS) and golden yellow stannic sulfide (SnS2), both of which are insoluble in water and dilute acids. Preparation and use.

It is commercially profitable to extract tin from placer deposits with a 0.01 percent Sn content and from native deposits with a 0.1 percent Sn content; most deposits contain tenths of a percent or only a few percentage units of tin. In ores, tin is often associated with W, Zr, Cs, Rb, and rare-earth elements, as well as with Ta, Nb, and other precious metals. The raw material from placer deposits is usually enriched by gravitation; table flotation or simple flotation is usually used with ores from native deposits. Concentrates, which contain from 50 to 70 percent tin, are roasted to facilitate sulfur extraction and treated with HCI to eliminate iron. If wolframite [(Fe, Mn)WO4] and scheelite (CaWO4) impurities are present, the concentrate is subjected to HCI treatment, and the resulting WO3 · H2O is removed with NH4OH. The concentrates are then smelted with coal in electric or combustion furnaces to produce crude tin, which is 94–98 percent tin and contains Cu, Pb, Fe, As, Sb, and Bi.

After smelting, the crude tin is filtered through coke at 500°–600°C or centrifuged to separate most of the iron from the mix. The addition of elemental sulfur to the liquid metal removes any remaining Fe and Cu impurities, which float up as solid sulfides and are subsequently removed from the surface of the tin. A similar refining process is employed to remove arsenic and antimony (in which case the additive is aluminum) or lead (with the additive SnCl2). Sometimes Bi and Pb are evaporated under a vacuum. Electrolytic refining and recrystallization are only used in certain rare cases where especially pure tin is required. Approximately 50 percent of all the tin that is produced is secondary metal, which is prepared from the waste products of tin-plating, from scrap metal, and from various alloys. Up to 40 percent is used for the tin-plating of food cans, and the remainder is used to manufacture solders, bearing alloys, and type metals. Stannic oxide serves in the preparation of heat-resistant enamels and glazes.

Sodium stannite (Na2SnO3 · 3H2O) is used for the mordant dyeing of textiles. Crystalline SnS2, or gold plate, is combined with paints and applied to produce a gilded effect. Niobium stannide (Nb3Sn) is a very popular superconductor. N. N. S EVRIUKOV Toxicity. Tin, either alone or in combination with most inorganic substances, exhibits relatively low toxicity. Very few cases of acute poisoning have been induced by the wide use of elemental tin in industry. According to current scientific literature, individual cases of tin poisoning are apparently caused by the liberation of AsH3 when water accidentally falls on the waste material that forms during the removal of arsenic impurities from tin. Workers in tin-smelting plants may develop symptoms of pneumoconiosis from prolonged exposure to stannous oxide dust, or “black tin.” Cases of chronic eczema are sometimes known to occur among workers who prepare tin foil.

Atmospheric concentrations of tin tetrachloride (SnCl4 · 5H2O) that exceed 90 mg/m3 irritate the upper respiratory tract and induce coughing, and tin chloride causes ulceration upon contact with skin. Stannic hydride (SnH4) is a strong convulsive poison, but the chances of its formation under industrial conditions are very slight. Severe poisoning after ingestion of canned foods that have been subjected to prolonged storage may be related to the formation of SnH4 in the containers, which is the result of the behavior of organic acids in the food during tinning. Acute SnH4 poisoning induces convulsions, equilibrium disorders, and even death. Organic tin compounds, particularly dialkyls and trialkyls, exhibit a marked effect on the central nervous system. Symptoms of trialkyl poisoning include headache, vomiting, dizziness, convulsions, paresis, paralysis, and disturbances in vision; these are frequently followed by coma and fatal respiratory and cardiac failures. Dialkyl tin compounds exhibit slightly lower toxicity, and the poisoning is characterized by disorders of the liver and bile ducts. Industrial hygiene regulations should be followed to prevent tin poisoning.

Tin as an artistic material. Tin has been used in the decorative and applied arts because of its excellent casting properties, malleability, suitability for cutting, and brilliant silver-white color. The ancient Egyptians soldered tin onto various metals for ornamental purposes. Toward the end of the 13th century, Western Europeans began to fashion tin dishes and church wares that resembled silver articles but had smoother contours and deeper, more rounded lines in the etchings used for inscriptions and ornamentation. In the 16th century, F. Briot in France and C. Enderlein in Germany were the first to mold ornamental cups, plates, and goblets from tin; the relief figures were in the form of crests and scenes from mythology and daily life. A. Sh. Bul’ used tin as a decorative trim on furniture. Tin mirror frames and utensils enjoyed widespread popularity in 17th-century Russia. The manufacture of copper trays, kettles, and snuffboxes trimmed with tin inlay and enamel flourished in Northern Russia during the 18th century.

Toward the beginning of the 19th century, tin wares were gradually replaced by faience, resulting in the near disappearance of tin from the decorative-art market and the increasingly rare use of the metal for ornamental purposes. The high aesthetic value of modern tin ornaments stems from the sharp outlines of the shapes in objects and from the mirror finish, which is obtained by casting without subsequent processing.

It is a soft, silvery white metal with a bluish tinge, known to the ancients in bronze, an alloy with copper . Tin is widely used for plating steel cans used as food containers, in metals used for bearings, and in solder. The origins of tin are lost in antiquity. Bronzes , which are copper–tin alloys, were used by humans in prehistory long before pure tin metal itself was isolated. Bronzes were common in early Mesopotamia , the Indus valley, Egypt, Crete, Israel, and Peru . Much of the tin used by the early Mediterranean peoples apparently came from the Scilly Isles and Cornwall in the British Isles , where tin mining dates to at least 300–200 bce.

Tin mines were operating in both the Inca and Aztec domains of South and Central America before the Spanish conquest. The symbol Sn for tin is an abbreviation of the Latin word for tin, stannum. Occurrence and distribution The element is present in the igneous rocks of Earth’s crust to the extent of about 0.001 percent, which is scarce but not rare; its abundance is of the same order of magnitude as such technically useful elements as cobalt , nickel , copper, cerium , and lead , and it is essentially equal to the abundance of nitrogen . In the cosmos there are 1.33 atoms of tin per 1 × 106 atoms of silicon , an abundance roughly equal to that of niobium , ruthenium , neodymium , or platinum . Cosmically, tin is a product of neutron absorption. Its richness in stable isotopes is noteworthy. carbon group element: Tin occurs in grains of the native metal but chiefly as stannic oxide, SnO2, in the mineral cassiterite , the only tin mineral of commercial significance. The metal is obtained from cassiterite by reduction (removal of the oxygen) with coal or coke in smelting furnaces.

No high-grade deposits are known. The major sources are alluvial deposits, averaging about 0.01 percent tin. The oldest tin mines were those in Cornwall, which were worked at least as early as Phoenician times but are no longer of major consequence, and Spain. Lode deposits, containing up to 4 percent, are found in Bolivia and Cornwall. China led the world in tin production in the early 21st century, accounting for nearly half of all production; Indonesia , Peru, and Bolivia were also top producers. Several processes have been devised for reclaiming the metal from scrap tin or tin-plated articles. (For a full treatment of tin mining, refining, and recovery, see tin processing .) Properties of the element carbon (C) Tin is nontoxic, ductile, malleable , and adapted to all kinds of cold-working, such as rolling , spinning , and extrusion . The colour of pure tin is retained during exposure because a thin, invisible, protective film of stannic oxide is formed spontaneously by reaction with the oxygen of the air.

The low melting point of tin and its firm adhesion to clean surfaces of iron , steel, copper, and copper alloys facilitate its use as an oxidation-resistant coating material. Tin exists in two different forms, or allotropes: the familiar form, white (or beta) tin, and gray (or alpha) tin, which is powdery and of little use. The gray form changes to the white above 13.2 °C (55.8 °F), rapidly at temperatures above 100 °C (212 °F); the reverse transformation, called tin pest, occurs at low temperatures and seriously hampers the use of the metal in very cold regions. This change is rapid only below −50 °C (−58 °F), unless catalyzed by gray tin or tin in the +4 oxidation state , but is prevented by small amounts of antimony , bismuth , copper, lead, silver , or gold normally present in commercial grades of tin. Periodic Table of the Elements White tin has a body-centred tetragonal crystal structure , and gray tin has a face-centred cubic structure.

When bent, tin makes an eerie, crackling “cry” as its crystals crush each other. Tin is attacked by strong acids and alkalies, but nearly neutral solutions do not affect it appreciably. Chlorine , bromine , and iodine react with tin, but fluorine reacts with it only slowly at room temperature. The relationships among the allotropic modifications of tin can be represented as transformations from one crystal type to another at specific temperatures: Britannica Stories Methane Surge Worries Scientists (The double arrows signify that the transformation occurs in both directions, as tin is heated or as it is cooled.) Tin exists in two oxidation states, +4 and +2. Elemental tin is readily oxidized to the dipositive ion in acidic solution, but this Sn2+ ion is converted to the Sn4+ ion by many mild oxidizing agents, including elemental oxygen. Oxidation under alkaline conditions normally gives the tetrapositive (Sn4+) state. In an alkaline medium, dipositive tin (Sn2+) disproportionates readily to tetrapositive tin and the free element.

Tin has 10 stable isotopes, occurring in the following percentages in natural tin: tin-112, 0.97; tin-114, 0.65; tin-115, 0.36; tin-116, 14.53; tin-117, 7.68; tin-118, 24.22; tin-119, 8.58; tin-120, 32.59; tin-122, 4.63; and tin-124, 5.79. Uses Tin-plating of iron protects the latter from corrosion; tin piping and valves maintain purity in water and beverages; molten tin is the base for (float) plate-glass production. Because pure tin is relatively weak, it is not put to structural uses unless alloyed with other metals in such materials as bronzes, pewter , bearing metals, type metals, lead-based solders, bell metal, babbitt metal , and low-temperature casting alloys.

Tin oxide , in which tin is in the +4 oxidation state, is useful in making ceramic bodies opaque , as a mild abrasive, and as a weighting agent for fabrics. Tin fluoride and tin pyrophosphate, in which tin is in the +2 oxidation state, are used in dentifrices. Organic tin compounds act as stabilizers in certain plastics and as wood preservatives. A crystalline alloy with niobium is a superconductor at temperatures as high as 18 K (−427 °F) and retains this property in very strong magnetic fields. Elemental tin is apparently nontoxic, and quantities of tin up to 300 parts per million, as dissolved by foods packaged in tin-plated containers and cooking utensils, are not harmful. Organic tin compounds commonly used as biocides and fungicides are, however, toxic to human beings. Compounds Facebook Twitter YouTube Instagram Pinterest Tin forms two series of compounds: stannous, in which tin is in the +2 oxidation state, and stannic, in which it is in the +4 state.

Some of the more commercially important stannous compounds are stannous chloride, SnCl2, used in tin galvanizing and as a reducing agent in the manufacture of polymers and dyes; stannous oxide, SnO, employed in making tin salts for chemical reagents and for plating; and stannous fluoride, SnF2, an active ingredient in toothpastes. Stannic compounds of significance include stannic chloride, SnCl4, widely used as a stabilizer for perfumes and as a starting material for other tin salts; and stannic oxide, SnO2, a useful catalyst in certain industrial processes and a polishing powder for steel. Tin can form a bond with carbon, as in the more than 500 known organotin compounds . Organotin stabilizers are used to prevent changes in polyvinyl chloride upon exposure to light and heat. A number of organotin compounds are major ingredients in biocides and fungicides. Element Properties
