History

History
The element Tungsten was discovered by Carl Wilhelm Scheele in year 1783 in Spain. Tungsten derived its name from from the Swedish tung sten, 'heavy stone' (W is wolfram, the old name of the tungsten mineral wolframite)
The element Molybdenum was discovered by Carl Wilhelm Scheele in year 1781 in Sweden. Molybdenum derived its name derived its name from from the Greek word molybdos meaning 'lead'
