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 Boron was discovered by Joseph Louis Gay-Lussac in year 1808 in France and United Kingdom. Boron derived its name derived its name from from borax, a mineral
