It is highly toxic and found in nature as the rare mineral shcherbinaite. Vanadium(V) oxide catalyses several useful aerobic oxidation reactions, most notably in the production of sulfuric acid from sulfur dioxide. Vanadium is a transition metal with the chemical symbol V and atomic number 23. The element usually combines with other elements such as oxygen, sodium, sulfur, or chloride, and occurs naturally in about 65 different minerals and in fossil fuel deposits. Vanadium is found in many organisms, and is used by some life forms as an active center of enzymes. (L837, L838, L849)"}]
