It is known to be the 3 rd transuranium element discovered yet. Facts about Curium 1: Glenn T. Seaborg. Named in honour of Pierre and Marie Curie. Curium is a radioactive element with atomic number 96 and element symbol Cm. Cerium is the most abundant of the rare earth elements and makes up about 0.0046% of the earth's crust. The element Curium was discovered by Glenn T. Seaborg in year 1944 in United States . Although curium follows americium in the periodic system, it was actually the third transuranium element to be discovered. A commitment to quality. So radioactive it glows in the dark. The sample of curium isolated by the group of Glenn T Seaborg was barely visible and was identified only by its radioactivity. Americium. See more. History. Curium was discovered by Glenn T. Seaborg, Ralph A. James and Albert Ghiorso at the University of California, Berkeley in 1944. The isotopes of curium such as curium- 244 and curium 242 are used in power generation industries such as thermo-electric and thermionic converters.
