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 Bromine was discovered by Antoine Jérôme Balard in year 1826 in France. Bromine derived its name derived its name from from the Greek bromos, meaning 'stench'
