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 Cadmium was discovered by Karl Samuel Leberecht Hermann in year 1817 in Germany. Cadmium derived its name derived its name from from the New Latin cadmia, from King Kadmos
