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.]

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.
