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 Tungsten was discovered by Carl Wilhelm Scheele in year 1783 in Spain. Tungsten derived its name derived its name from from the Swedish tung sten, 'heavy stone' (W is wolfram, the old name of the tungsten mineral wolframite)
