History

History

The element Ruthenium was discovered by Karl Ernst Claus in year 1844 in Russia. Ruthenium derived its name from from Ruthenia, the New Latin name for Russia

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'
