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 Aluminium was discovered by in year 1825 in Denmark. Aluminium derived its name derived its name from from alumina, a compound (originally aluminum)
