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 Yttrium was discovered by Johan Gadolin in year 1794 in Finland. Yttrium derived its name derived its name from from Ytterby, Sweden
