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 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 MeV); they have fairly short half-lives, 162.8 days and 18.1 years, and give as … See more • Greenwood, Norman N.; Earnshaw, Alan (1997).

While curium itself mostly emits α-particles which are absorbed by thin layers of common materials, some of its decay products … See more WebWe know that the atomic number of curium is 96 and the atomic average mass number is about 247. Neutron = 247 – 96 = 151. Therefore, a curium atom has one hundred fifty-one neutrons. Based on the atomic number, mass number, and neutron number of the element, three things can be considered. These are isotope, isobar, and isotone.
