About this element. In 1830, N. Sefström discovered vanadium in some iron ores. Vanadium is a white metal that possesses good resistance to corrosion by alkalis, sulfuric acid, and hydrochloric acid. Vanadium occurs in approximately sixty-five different minerals and in carbon deposits such as crude oil, coal, oil shale, and tar sands, but is ...

Abstract. Vanadium is a steel-grey, corrosion-resistant metal, which exists in oxidation states ranging from −1 to +5. Metallic vanadium does not occur in nature, and the most common valence states are +3, +4, and +5. The pentavalent form (VO 3 −) predominates in extracellular body fluids whereas the quadrivalent form (VO +2) is the …

Vanadium is an average-hard, ductile, steel-blue metal. It is electrically conductive and thermally insulating. Vanadium is usually described as "soft", because it is ductile, malleable, and not brittle.[16][17] Vanadium is harder than most metals and steels (see Hardnesses of the elements (data page) and iron). It has good resistance to ...
