History

History
The element Roentgenium was discovered by Gesellschaft für Schwerionenforschung in year 1994 in Germany. Roentgenium derived its name from from Wilhelm Conrad Röntgen, physicist
The element Osmium was discovered by Smithson Tennant in year 1803 in United Kingdom. Osmium derived its name derived its name from from the Greek osmè, meaning 'smell'
