History

ParameterArgonOxygen
HistoryThe element Argon was discovered by Lord Rayleigh and W. Ramsay in year 1894 in United Kingdom. Argon derived its name from the Greek word argos, meaning 'idle'.The element Oxygen was discovered by W. Scheele in year 1771 in Sweden and United Kingdom. Oxygen derived its name from the Greek word oxy-, both 'sharp' and 'acid', and -gen, meaning 'acid-forming'.
