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 Nickel was discovered by Axel Fredrik Cronstedt in year 1751 in Sweden. Nickel derived its name derived its name from from Swedish kopparnickel, containing the German word Nickel, 'goblin'
