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 Xenon was discovered by William Ramsay in year 1898 in United Kingdom. Xenon derived its name derived its name from from the Greek xenos, meaning 'strange'
