Etymology: Marie S. Curie; Pierre Curie
a radioactive metallic element. Its atomic number is 96. Its atomic mass is 247. Curium is an artificial element produced by bombarding plutonium with helium ions in a cyclotron. Numerous isotopes of curium are produced by bombarding lighter transuranium elements. Curium is so radioactive that it glows in the dark.
