Named after the University of California at Berkeley, berkelium is a silvery, radioactive metal. It is a chemically active metal, reacting with air, water and acids but not bases. It has never been found naturally and less than a gram is produced each year. Berkelium is too rare to have any commercial or industrial uses. The most stable isotope of berkelium has a half-life of 1,400 years.
