History

History
The element Iridium was discovered by Smithson Tennant in year 1803 in France and United Kingdom. Iridium derived its name from from Iris, the Greek goddess of the rainbow
The element Platinum was discovered by Antonio de Ulloa in year 1735 in Peru. Platinum derived its name derived its name from from the Spanish platina, meaning 'little silver'
