History

History
The element Roentgenium was discovered by Gesellschaft für Schwerionenforschung in year 1994 in Germany. Roentgenium derived its name from from Wilhelm Conrad Röntgen, physicist
The element Polonium was discovered by Pierre Curie in year 1898 in France. Polonium derived its name derived its name from from Named after the home country of Marie Curie(Poland), who is also the discoverer of Radium
