Below are some physical and chemical properties of curium. State: Solid. Curium atomic radius is N/A, while it's covalent radius is N/A. Here, A suggests alkali metals. Isotopes 19 radioisotopes of curium have been characterized, with the most stable being Cm-247 with a half-life of 1.56 × 10 7 years, Cm-248 with a half-life of 3.40 × 10 5 years, Cm-250 with a half-life of … Curium is a synthetic radioactive element that was first produced in laboratory. Curium was made in its elemental form in 1951 for the first time. The boiling point of curium is 3556 °C. Electron configuration- Rn 5f7 6d2 7s2 Curium was discovered in 1944, by Glenn T. Seaburg, Ralph A. James, and Chiorso, at the Univeristy of California, Berkeley. Curium isotopes like Cm–242 and Cm–244 find their usages in the industry of power generation.
