History

ParameterHydrogenOxygen
HistoryThe element Hydrogen was discovered by H. Cavendish in year 1766 in United Kingdom. Hydrogen derived its name from the Greek elements hydro- and -gen meaning 'water-forming'.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'.
