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 Tellurium was discovered by Franz-Joseph Müller von Reichenstein in year 1783 in Romania. Tellurium derived its name derived its name from from Latin tellus, meaning 'earth'
