History

History
The element Hydrogen was discovered by Henry Cavendish in year 1766 in United Kingdom. Hydrogen derived its name from from the Greek elements hydro- and -gen meaning 'water-forming'
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'
