Definition of 'curium'
From: GCIDE
- curium \curium\ n. [after Pierre and Marie Curie.] a radioactive transuranic element of atomic number 96, having an atomic weight of 247 for its most stable isotope (half-life 1.6 x 10^7 years). The chemical symbol is Cm.
- Note: It was first prepared in 1944 by helium-ion bombardment of plutonium in a cyclotron by Glenn Seaborg and colleagues in California. It has never been detected in nature, though minute quantities may exist in uranium deposits as a consequence of the neutron flux there.
- Syn: Cm, atomic number 96. [WordNet 1.5]

- Radioactive metallic transuranic element. Belongs to actinoid series. Nine known isotopes, Cm-247 has a half-life of 1.64*10^7 years. First identified by Glenn T. Seaborg and associates in 1944, first produced by L.B. Werner and I. Perlman in 1947 by bombarding americium-241 with neutrons. Named for Marie Curie.
