Curium Element Properties, Uses, Information, Facts
Webcurium (Cm), synthetic chemical element of the actinoid series of the periodic table, atomic number 96. Unknown in nature, curium (as the isotope curium-242) was discovered (summer 1944) at the University of … Curium is a transuranic, radioactive chemical element with the symbol Cm and atomic number 96. This actinide element was named after eminent scientists Marie and Pierre Curie, both known for their research on radioactivity. Curium was first intentionally made by the team of Glenn T. Seaborg, Ralph A. James, and … See more Though curium had likely been produced in previous nuclear experiments as well as the natural nuclear fission reactor at Oklo, Gabon, it was first intentionally synthesized, isolated and identified in 1944, at University of California, Berkeley See more Oxides Curium readily reacts with oxygen forming mostly Cm2O3 and CmO2 oxides, but the divalent oxide CmO is also known. Black CmO2 can be obtained by burning curium oxalate (Cm 2(C 2O 4) 3), nitrate (Cm(NO 3) 3), or hydroxide … See more Due to its radioactivity, curium and its compounds must be handled in appropriate labs under special arrangements. … See more • Greenwood, Norman N.; Earnshaw, Alan (1997).
