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 Bismuth was discovered by Claude François Geoffroy in year 1400 in unknown place. Bismuth derived its name derived its name from from German word, now obsolete
