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 Fluorine was discovered by André-Marie Ampère in year 1886 in France. Fluorine derived its name derived its name from from the Latin fluere, meaning 'to flow'
