Such an arrangement helps explain the periodicity and periodic trends observed across the elements of the periodic table. However, you can also find several use of Cm in medical fields. 1. It is a radioactive metal. Highly toxic. When curium glows, you will notice a dark pink or purple colour. Therefore, one of the 4s2 electrons jumps to the 3d5 so that it is half-filled (see video below). Curium, a trans-uranic element, was first discovered by Glenn Seaborg and collaborators at the University of California, Berkeley. APXS spectrometer can convert nuclear energy into electricity. Curium was created by covering a piece of element, known as plutonium with alpha particles.
