However, three elements, Thorium, Protactinium, and Uranium, have a characteristic terrestrial isotopic composition, and thus their atomic mass given. 7Aluminum; see AluminiumAlAmericiumAm95[243] 7Antimony (Stibium)Sb51121.760(1)The isotopic composition of this element varies in some geological specimens, and the variation may exceed the uncertainty stated in the table.155Argentum—see SilverAgArgonAr1839.948(1)The isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given.183ArsenicAs3374.92160(2)154AstatineAt85[210]176Aurum—see GoldAuBariumBa56137.327(7)26BerkeliumBk97[247] 7BerylliumBe49.012182(3)22BismuthBi83208.98040(1)156BohriumBh107[264]77BoronB510.811(7)The isotopic composition of the element can vary in commercial materials, which can cause the atomic weight to deviate significantly from the given value.132BromineBr3579.904(1)174CadmiumCd48112.411(8)125Caesium (Cesium)Cs55132.9054519(2)16CalciumCa2040.078(4)24CaliforniumCf98[251] 7CarbonC612.0107(8)142CeriumCe58140.116(1) 6Cesium—see CaesiumCsChlorineCl1735.453(2)173ChromiumCr2451.9961(6)64CobaltCo2758.933195(5)94Copper (Cuprum)Cu2963.546(3)114CuriumCm96[247] 7DarmstadtiumDs110[271]107DubniumDb105[262]57DysprosiumDy66162.500(1) 6EinsteiniumEs99[252] 7ErbiumEr68167.259(3) 6EuropiumEu63151.964(1) 6FermiumFm100[257] 7Ferrum—see IronFeFluorineF918.9984032(5)172FranciumFr87[223]17GadoliniumGd64157.25(3) 6GalliumGa3169.723(1)134GermaniumGe3272.64(1)144Gold (Aurum)Au79196.966569(4)116HafniumHf72178.49(2)46HassiumHs108[277]87HeliumHe24.002602(2)181HolmiumHo67164.930 32(2) 6Hydrargyrum—see MercuryHgHydrogenH11.00794(7)11IndiumIn49114.818(3)135IodineI53126.904 47(3)175IridiumIr77192.217(3)96Iron (Ferrum)Fe2655.845(2)84Kalium—see PotassiumKKryptonKr3683.798(2)184LanthanumLa57138.90547(7) 6LawrenciumLr103[262]37Lead (Plumbum)Pb82207.2(1)146LithiumLi36.941(2)The atomic weight of commercial Lithium can vary between 6.939 and 6.996—analysis of the specific material is necessary to find a more accurate value.12LutetiumLu71174.967(1)36MagnesiumMg1224.3050(6)23ManganeseMn2554.938045(5)74MeitneriumMt109[268]97MendeleviumMd101[258] 7Mercury (Hydrargyrum)Hg80200.59(2)126MolybdenumMo4295.94(2)65Natrium—see SodiumNaNeodymiumNd60144.242(3) 6NeonNe1020.1797(6)182NeptuniumNp93[237] 7NickelNi2858.6934(2)104NiobiumNb4192.906 38(2)55NitrogenN714.0067(2)152NobeliumNo102[259] 7OsmiumOs76190.23(3)86OxygenO815.9994(3)162PalladiumPd46106.42(1)105Plumbum—see LeadPbPhosphorusP1530.973762(2)153PlatinumPt78195.084(9)106PlutoniumPu94[244] 7PoloniumPo84[210]166Potassium (Kalium)K1939.0983(1)14PraseodymiumPr59140.90765(2) 6PromethiumPm61[145] 6ProtactiniumPa91231.03588(2) 7RadiumRa88[226]27RadonRn86[220]186RheniumRe75186.207(1)76RhodiumRh45102.905 50(2)95RoentgeniumRg111[272]117RubidiumRb3785.4678(3)15RutheniumRu44101.07(2)85RutherfordiumRf10426147SamariumSm62150.36(2) 6ScandiumSc2144.955912(6)34SeaborgiumSg106[266]67SeleniumSe3478.96(3)164SiliconSi1428.0855(3)143Silver (Argentum)Ag47107.8682(2)115Sodium (Natrium)Na1122.98976928(2)13Stannum—see TinSnStibium—see AntimonySbStrontiumSr3887.62(1)25SulfurS1632.065(5)163TantalumTa73180.94788(2)56TechnetiumTc43[98]75TelluriumTe52127.60(3)165TerbiumTb65158.92535(2) 6ThalliumTl81204.3833(2)136ThoriumTh90232.03806(2) 7ThuliumTm69168.93421(2) 6Tin (Stannum)Sn50118.710(7)145TitaniumTi2247.867(1)44Tungsten (Wolfram)W74183.84(1)66UnunbiumUub112[285]127UnunhexiumUuh116[292]167UnunoctiumUuo118[294]187UnunpentiumUup115[288]157UnunquadiumUuq114[289]147UnuntriumUut113[284]137UraniumU92238.02891(3) 7VanadiumV2350.9415(1)54Wolfram—see TungstenWXenonXe54131.293(6)185YtterbiumYb70173.04(3) 6YttriumY3988.90585(2)35ZincZn3065.409(4)124ZirconiumZr4091.224(2)45   মন্তব্য    তথ্যসূত্র   Atomic Weights of the Elements 2001, Pure Appl.
