The newest element named .... Copernicum

The newest element on the periodic table will likely be named in honor of scientist and astronomer Nicolaus Copernicus. Element 112 will be named Copernicum, with the element symbol "Cp."

Thirteen years ago, element 112 was discovered by an international team of scientists at the GSI Helmholtzzentrum für Schwerionenforschung (Center for Heavy Ion Research) in Darmstadt, Germany.

The element is produced by a nuclear fusion, when bombarding zinc ions onto a lead target. As the element already decays after a split second, its existence can only be proved with the help of extremely fast and sensitive analysis methods. Twenty-one scientists from Germany, Finland, Russia and Slovakia have been involved in the experiments that led to the discovery of element 112.

Since 1981, GSI accelerator experiments have yielded the discovery of six chemical elements, which carry the atomic numbers 107 to 112. The discovering teams at GSI already named five of them: element 107 is called bohrium, element 108, hassium; element 109, meitnerium; element 110, darmstadtium; and element 111 is named roentgenium
