What the name means: Curium was named after the chemists and Nobel Laureates, Pierre and Marie Curie who were pioneers in investigating radio-active elements in the actinide series - actinium (element # 89) to lawrencium (element # 103).
Who identified curium?: Glenn Theodore Seaborg, Ralph Arthur James and their co-workers, working on the Manhattan Project in a Chicago Laboratory, produced curium in 1947 by bombarding plutonium atoms with neutrons. It was isolated in the same year by Isadore Perlman and Louis Werner working at the Lawrence Berkeley Laboratories.
STP = standard temperature and pressure.
