Fermium: the essentials

Fermium's chemical properties are largely unknown. Fermium is a radioactive rare earth metal. The longest living isotope is is 257Fm with a half-life of 80 days. It is of no commercial importance.

Fermium: historical information

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

Fermium was identified by Ghiorso and coworkers (Berkeley, California, USA) in 1952 in the radioactive debris from a thermonuclear explosion in the Pacific. Somewhat remarkably, the fermium isotope discovered was made through the combination of 238U with 17 neutrons. Today, many isotopes are known spanning the mass range 243-258.
