Classification Transition


Copernicium is the newest element to be named, having been recognized by the IUPAC on February 19, 2010. It is named after Copernicus, who originated the model of the solar system as planets moving around the sun - a model that inspired the Bohr model of the atom.[1] Copernicium does not occur in nature; it was first discovered in 1996 at the Centre for Heavy Ion Research in Germany while bombarding a lead target with zinc ions. The isotope discovered decays in less than a second.[2]
