History

History
The element Molybdenum was discovered by Carl Wilhelm Scheele in year 1781 in Sweden. Molybdenum derived its name from from the Greek word molybdos meaning 'lead'
The element Thorium was discovered by Jöns Jakob Berzelius in year 1829 in Sweden. Thorium derived its name derived its name from from Thor, the Scandinavian god of thunder
