History

History
The element Promethium was discovered by Chien Shiung Wu in year 1945 in United States. Promethium derived its name from from Prometheus of Greek mythology who stole fire from the Gods and gave it to humans
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)
