Vanadium is a chemical element; it has symbol V and atomic number 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.
Vanadium (chemical symbol V, atomic number 23) is a rare, silver-gray metal. It is found combined in several minerals and is one of the 26 elements that commonly occur in living things. It is used mainly in various alloys. For instance, it is an additive in specialty stainless steel for surgical instruments and high-speed tools.
