History

History
The element Darmstadtium was discovered by Gesellschaft für Schwerionenforschung in year 1994 in Germany. Darmstadtium derived its name from from Darmstadt, Germany, where the element was first synthesized
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'
