Einsteinium: the essentials

Einsteinium is radioactive rare earth metal named after Albert Einstein. It is of no commercial importance and only a few of its compounds are known.

Einsteinium: historical information

Einsteinium was discovered by Workers at Argonne, Los Alamos, USA, and the University of California at Berkeley, USA. in 1952 at USA. Origin of name: named after "Albert Einstein".

Einsteinium was identified by Ghiorso and others (Berkeley, California, USA) in 1952 in radioactive debris from the first large thermonuclear bomb explosion, which took place in the Pacific in November 1952. In 1961, a sufficient amount of einsteinium was produced to permit separation of a macroscopic amount of 253Es.
