cal·i·for·ni·um

 (kăl′ə-fôr′nē-əm)
n. Symbol Cf
A synthetic transuranic element having isotopes with mass numbers from 237 to 256 and half-lives varying from 21 milliseconds to 898 years. All isotopes are radioactive, chiefly by emission of alpha particles, and Cf-252 is a potent neutron emitter. Atomic number 98; melting point 900°C; specific gravity 15.1; valence 3. See Periodic Table.

[After California.]

(ˌkælɪˈfɔːnɪəm)
n
(Elements & Compounds) a metallic transuranic element artificially produced from curium. Symbol: Cf; atomic no: 98; half-life of most stable isotope, 251Cf: 800 years (approx.)
[C20: New Latin; discovered at the University of California]

cal·i·for·ni·um

(kăl′ə-fôr′nē-əm)
Symbol Cf A synthetic, radioactive metallic element of the actinide series that is produced from curium or berkelium. Californium emits a large number of neutrons and is used in the analysis of chemical components of substances. Its most stable isotope has a half-life of 800 years. Atomic number 98.

Seaborg, one of the great scientific minds of this time and of all times, chaired the Academic Standards Commission's Science Committee." Seaborg, an American chemist who died in 1999, played a central role in discovering and isolating ten transuranic elements (including plutonium, americam, and californium), worked on the Manhattan Project, proposed the addition of the actinide series to the Periodic Table, shared the Nobel Prize in Chemistry in 1951, and served as chancellor of University of California, Berkeley and chairman of the United States Atomic Energy Commission (http://en.wikipedia.org/Glenn_t._Seaborg).
