Berkelium: the essentials
Berkelium is a radioactive rare earth metal, named after the University of California at Berkeley (USA). Apparently, berkelium tends to accumulate in the skeletal system. It is of no commercial importance and only a few of its compounds are known.
Berkelium: historical information
Berkelium was discovered in December 1949 at Berkeley, Californi, USA, by Ghiorso and others by cyclotron bombardment of milligram amounts of americium with helium ions. Perhaps the first visible amounts of a pure berkelium compound, berkelium chloride, was produced in 1962. It weighed just 3 billionth of a gram.
