History

On February 9, 1996, element 277Cn was created at the Gesellschaft fur Schwerionenforschung in Darmstadt, Germany by using the reaction 208Pb + 70Zn. Unlike element 110, Copernicium has properties more similar to radon than mercury, but due to its short half-life, it is difficult to study. As of 2011, Copernicum's most stable isotope has an atomic weight of 285.
