(gcide) | fermium \fermium\ n.
the transuranic element of atomic number 100; symbol Fm. The
atomic weight of the most stable isotope, having a half-life
of about 80 days, is 257. The first isotope, Fm255 was
discovered in 1952 in the debris of a thermonuclear
explosion. Other istopes have been produced in nuclear
reactors and by decay of other transuranic elements. --Handb.
Ch. Phys. 61.
Syn: Fm.

Radioactive metallic transuranic element, belongs to the actinoids. Ten
known isotopes, most stable is Fm-257 with a half-life of 10 days. First
identified by Albert Ghiorso and associates in the debris of the first
hydrogen-bomb explosion in 1952.
