The Beautiful Element: Vanadium

　The element vanadium has named after the Scandinavian goddness, the god of beauty, love and maturity, Vanadis. It is avandant in sea-water and it is important in industry as catalyst, an additive to steel and new materials. In chemistry, the solution containing vanadium complexes is known to exhibit a spectrum of a beautiful color. This is because of the possible versatile oxidation states in vanadium as well as the coordination spheres. Especially, a square-pyramidal five coordination mode is particularly important only in vanadium.
