Vanadium
Three bars of pure vanadium in various states of oxidation made using the crystal bar process, and a 1 cm3 cube of it for comparison. Vanadium is a hard, silvery gray, ductile and malleable transition metal named after Vanadís, the Germanic equivalent of the Norse goddess Freyja. In nature, vanadium only exists in chemically combined form.Photo: Alchemist-hp
