History

History
The element Rubidium was discovered by Robert Bunsen in year 1861 in Germany. Rubidium derived its name from from the Latin rubidus, meaning 'deep red'
The element Lutetium was discovered by Georges Urbain in year 1907 in France and Germany. Lutetium derived its name derived its name from from Lutetia, the Latin name for Paris
