History

History
The element Oxygen was discovered by Carl Wilhelm Scheele in year 1774 in Sweden and United Kingdom. Oxygen derived its name from from the Greek word oxy-, both 'sharp' and 'acid', and -gen, meaning 'acid-forming'
The element Promethium was discovered by Chien Shiung Wu in year 1945 in United States. Promethium derived its name derived its name from from Prometheus of Greek mythology who stole fire from the Gods and gave it to humans
