V - Vanadium

A transition metal discovered in 1801 by Andreas del Rio in Mexico. The major use of the element is in hardened steels. Pure vanadium is a greyish silvery metal, and is soft and ductile. It has good corrosion resistance to alkalis, sulphuric acid, hydrochloric acid, and salt waters. The metal oxidizes readily above 660°C to form V2O5.
