Einsteinium

Chemical Formula

Es

Background

Einsteinium was identified by Ghiorso and co-workers in 1952 in debris from the large thermonuclear or “hydrogen” bomb explosion. Einsteinium is the seventh transuranic element of the actinide series to be discovered. The isotope produced was the 20-day 253Es.

Fourteen isotopes of einsteinium are recognised. 254Es has the longest half-life of 275 days. Tracer studies using 253Es show that einsteinium has chemical properties typical of a heavy trivalent, actinide element.

It has no known commercial applications.
