History
| Parameter | Osmium | Nickel |
|---|---|---|
| History | The element Osmium was discovered by S. Tennant in year 1803 in United Kingdom. Osmium derived its name from the Greek osmè, meaning 'smell'. | The element Nickel was discovered by F. Cronstedt in year 1751 in Sweden. Nickel derived its name from Swedish kopparnickel, containing the German word Nickel, 'goblin'. |
