Vanadium - Wikipedia

Vanadium is a chemical element with the syol V and atomic nuer 23. It is a hard, silvery-grey, 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 .
