Vanadium is a chemical element with symbol V and atomic number 23. It is a hard, silvery-grey, ductile, and 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.
