History

History
The element Technetium was discovered by Emilio Segrè in year 1937 in Italy. Technetium derived its name from from the Greek tekhnètos meaning 'artificial'
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
