Vanadium (V) - Chemical properties, Health and

Vanadium is a rare, soft, ductile gray-white element found combined in certain minerals and used mainly to produce certain alloys. Vanadium resists corrosion due to a protective film of oxide on the surface. Common oxidation states of vanadium include +2, +3, +4 and +5. Applications Chemical Properties of Vanadium Pure vanadium is stable and retains its lustre in damp air. On being rapidly heated in a stream of oxygen the powdered metal burns, forming vanadium pentoxide, V2O5; the reaction is, however, incomplete. At a bright red heat the metal combines with nitrogen to form a nitride Element Vanadium (V), Group 5, Atomic Number 23, d-block, Mass 50.942.

Chemical properties Vanadium is moderately reactive. It does not react with oxygen in the air at room temperatures, nor does it dissolve in water. It does not react with some acids, such as hydrochloric or cold sulfuric acid. But it does become more reactive with hot acids, such as hot sulfuric and nitric acids Vanadium was rediscovered by Nils Gabriel Sefstrôm, a Swedish chemist, in 1830 while analyzing samples of iron from a mine in Sweden. Vanadium was isolated by Sir Henry Enfield Roscoe, an English chemist, in 1867 by combining vanadium trichloride (VCl 3) with hydrogen gas (H 2)
