HISTORY, BACKGROUND & USES:
Discovered in 1944 by Glenn T. Seaborg, Ralph A. James, and Albert Ghiorso. Curium is a radioactive element that has a silvery color. Isotopes 242 and 244 are suited for use in space because they can be used as compact, long-lived sources of electricity from the conversion of heat from radioactive decay by thermoelectric and thermoionic devices.
