Copernicium Bohr ModelCopernicium is a D-Block, Group 12, Period 7 element. The number of electrons in each of Copernicium's shells is 2, 8, 18, 32, 32, 18, 2 and its electron configuration is [Rn] 5f14 6d10 7s2. In its elemental form, Copernicium's CAS number is 54084-26-3. Copernicium was discovered in 1996 at the Institute for Heavy Ion Research (Gesellschaft für Schwerionenforschung (GSI)) in Darmstadt, Germany by Sigurd Hofmann, Peter Armbruster and Gottfried Münzenberg. Copernicium is a synthetic element that is not present in the environment. Little is known about the element, its appearance is unknown, and it has no known uses. Copernicium was named in honor of the sixteenth century scientist Nicolaus Copernicus.
