History

History
The element Germanium was discovered by Clemens Winkler in year 1886 in Germany. Germanium derived its name from from Germania, the Latin name for Germany
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'
