WebProperties of Curium. Curium was assigned the chemical symbol Cm. It has the atomic number 96, meaning it has 96 protons in its nucleus. Curium is also the 96th element on the periodic table. WebOxides. Curium readily reacts with oxygen forming mostly Cm 2 O 3 and CmO 2 oxides, but the divalent oxide CmO is also known. Black CmO 2 can be obtained by burning curium oxalate (Cm 2 (C 2 O 4) 3), nitrate (Cm(NO 3) 3), or hydroxide in pure oxygen. Upon heating to 600–650 °C in vacuum (about 0.01 Pa), it transforms into the whitish Cm 2 O 3: +. Or, …
