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 Cesium was discovered by Robert Bunsen in year 1860 in Germany. Cesium derived its name derived its name from from the Latin caesius, meaning 'sky blue'
