    — Curium was the third transuranium element to be discovered. The first isotope of this element was the isotope, Cm²⁴², which was identified by G. T. Seaborg, R. A. James and A. Ghiorso at the Metallurgical Laboratory as the result of its production in the Berkeley cyclotron […] The availability of this isotope of curium made it possible to study the chemical properties of this element by the use of the tracer technique. Extensive investigations have led to the conclusion that curium probably exists exclusively in the III oxidation state in aqueous solution.

词源

From Curie + -ium (suffix forming names of metallic elements), coined by the American scientists Glenn T. Seaborg (1912–1999), Ralph A. James (1920–1973), and Albert Ghiorso (1915–2010), who synthesized the element in 1944 and named it in honour of Pierre Curie (1859–1906) and Marie Skłodowska Curie (1867–1934) who, with Henri Becquerel, were awarded the 1903 Nobel Prize in Physics for discoveries in radioactivity.
