Curium ions are hard Lewis acids and thus form most stable complexes with hard bases. The bonding is mostly ionic, with a small covalent component. Curium in its complexes commonly exhibits a 9-fold coordination environment, with a tricapped trigonal prismatic molecular geometry. Isotopes 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 physical and chemical properties resembling gadolinium. Its melting point of 1344 °C is significantly higher than that of … 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 … See more Due to its radioactivity, curium and its compounds must be handled in appropriate labs under special arrangements. While curium itself mostly emits α-particles … 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, by Glenn T. Seaborg See more Isotope preparation Curium is made in small amounts in nuclear reactors, and by now only kilograms of Cm and Cm have been accumulated, and … See more Radionuclides Curium is one of the most radioactive isolable elements. Its two most common isotopes Cm and Cm are strong alpha emitters (energy 6 … See more WebFeb 14, 2024 · Curium -247 is the most stable isotope and has a half-life of about 15,600,000 years. This isotope also undergoes alpha decay and it decays into plutonium-243. History of Curium Curium was...
