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 Polonium was discovered by Pierre Curie in year 1898 in France. Polonium derived its name derived its name from from Named after the home country of Marie Curie(Poland), who is also the discoverer of Radium
