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 Gold was discovered by Middle East in year 2500 BC in unknown place. Gold derived its name derived its name from from English word (aurum in Latin)
