Vanadium Wikipedia

Vanadium is a chemical element with symbol V and atomic number 23. It is a hard, silverygrey, ductile, malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.
