### element | metal:

Titanium metal
* has some very valuable properties.
* is considered to be physiologically inert.

### element | metal | titanium:

Titanium tetrachloride
* clear, colorless liquid when kept in a sealed container.
* colorless to light-yellow liquid with a pungent odor
  - pale yellow liquid that has fumes with a strong odor
* is chemical compounds
  - used to iridize glass

Toxic metal
* Some toxic metal causes health problems
  - major health problems
* are everywhere, putting a constant strain on our cells
  - of concern in areas where water bodies receive heavy concentrations of acid rain
* can be abundant in some sewage sludges
  - increase the production of free radicals
* causes lumps in breast.
* have a variety of harmful effects.

Trace metal
* Some trace metal includes irons.
* are important elements, both from nutritional and toxicological points of view
  - part of the fundamental building blocks of the earth

### element | metal | tungsten:

Pure tungsten
* is quite brittle and difficult to machine
  - relatively soft and can be cut with a hacksaw
* steel gray to tin-white metal.

### element | metal:

Uranium
* All uranium is radioactive.
* Some uranium is mined, and Hungary is one of the world's most important bauxite producers
  - produced by direct chemical extraction rather than mining
  - leaves the body via the urine and can bemeasured by isotopic separtation
* can form solids solutions and intermetallic compounds with many of the metals.
* combines with oxygen to form water-soluble uranium salts.
* continues to decay into a stable lead isotope.
* emits radiation.
* exists naturally in the body and is transported in solution.
* gives off radioactivity.
* includes atoms.
* is chemical elements
  - metallic elements
  - of great importance as a nuclear fuel
  - radioactive substances
  - used for nuclear power
* occurs in nature in combination with small amounts of other elements
  - numerous minerals, such as pitchblende and carnotite
* poses very little risk as long as it is outside the body.
* reacts with acids and water much more easily than thorium.
* turns blue in air because it develops an oxide coating.

Uranium metal
* has very high density.
* is unaffected by alkalis.

### element | metal | uranium:

Natural uranium
* exists in the soil at a concentration of about four parts per million.
* has three isotopes in different ratios.
* is inhaled daily in very small amounts by all persons
  - sufficiently radioactive to expose a photographic plate in an hour or so
* mixture of three isotopes, or atomic strains, of the element.
* silver-colored metal that is radioactive.

Pure uranium
* is easily, chemically, refined from that.
* silvery white, weakly radioactive metal, which is harder than most elements.

Vanadium
* Most vanadium is used as a steel alloy called ferrovanadium.
* is metal
* works like insulin, increasing the uptake of glucose by cells for use as energy.

### element | metal | vanadium:

Chrome vanadium
* is formed by combining chemicals in different proportions.
* special kind of steel formed by combining different alloys.

Pure vanadium
* bright white metal, and is soft and ductile.
* greyish silvery metal, and is soft and ductile.
* has no smell.
