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 Erbium was discovered by Carl Gustaf Mosander in year 1842 in Sweden. Erbium derived its name derived its name from from Ytterby, Sweden
