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 Rubidium was discovered by Robert Bunsen in year 1861 in Germany. Rubidium derived its name derived its name from from the Latin rubidus, meaning 'deep red'
