Curium boils at 3556 °C. With a density of 13.52 g/cm 3, curium is lighter than neptunium (20.45 g/cm 3) and plutonium (19.8 g/cm 3 ), but heavier than most other metals. Of two crystalline forms of curium, α-Cm is more stable at ambient conditions. See more 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 … See more Physical A synthetic, radioactive element, curium is a hard, dense metal with a silvery-white appearance and … 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.
