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 Mercury was discovered by unknown in year 1500 BC in unknown place. Mercury derived its name derived its name from from the New Latin name mercurius, named after the Roman god (Hg from former name hydrargyrum, from Greek hydr-, 'water', and argyros, 'silver')
