History

History

The element Rubidium was discovered by Robert Bunsen in year 1861 in Germany. Rubidium derived its name from from the Latin rubidus, meaning 'deep red'

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'
