fermium    音标拼音: [f'ɛrmiəm]
n. 镄

□

fermium
n 1: a radioactive transuranic metallic element produced by
bombarding plutonium with neutrons [synonym: {fermium}, {Fm},
{atomic number 100}]

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.
