History

History
The element Barium was discovered by Carl Wilhelm Scheele in year 1808 in United Kingdom. Barium derived its name from from the Greek barys, meaning 'heavy'
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'
