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 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)
