Curium was discovered by Glenn T. Seaborg, Ralph A. James & Albert Ghiorso in 1944. It was identified by Seaborg, James, and Ghiorso in 1944 at the wartime metallurgical laboratory at the University of Chicago as a result of helium-ion bombardment of 239 Pu in the … The isotope curium-248 has been synthesized only in milligram quantities, but curium-242 and curium-244 are made in multigram amounts, which allows for the determination of some of the element's properties. Although curium follows americium in the periodic system, it was actually the third transuranium element to be discovered. Curium was first produced in 1944 at the University of California, Berkeley in the USA in a cyclotron by bombarding plutonium-239 239 Pu) with α-particles. It is a radioactive element that does not exist in nature. It was named after a French scientist. Curium is a chemical element with atomic number 96 which means there are 96 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. Curium is a hard, brittle, silvery metal that tarnishes slowly in dry air at room temperature.
