History

History
The element Copernicium was discovered by Gesellschaft für Schwerionenforschung in year 1996 in Germany. Copernicium derived its name from from Nicolaus Copernicus, astronomer
The element Astatine was discovered by Dale R. Corson in year 1940 in United States. Astatine derived its name derived its name from from the Greek astatos, 'unstable'
