History

History
The element Antimony was discovered by unknown in year 3000 BC in unknown place. Antimony derived its name from from the Greek anti, 'against', and monos, 'alone' (stibium in Latin)
The element Technetium was discovered by Emilio Segrè in year 1937 in Italy. Technetium derived its name derived its name from from the Greek tekhnètos meaning 'artificial'
