History

History
The element Osmium was discovered by Smithson Tennant in year 1803 in United Kingdom. Osmium derived its name from from the Greek osmè, meaning 'smell'
The element Radon was discovered by Friedrich Ernst Dorn in year 1900 in Germany. Radon derived its name derived its name from From radium, as it was first detected as an emission from radium during radioactive decay
