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 Gold was discovered by Middle East in year 2500 BC in unknown place. Gold derived its name derived its name from from English word (aurum in Latin)
