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