Word origin
The word 'oxygen' was coined by Antoine Lavoisier in the 18th century, based on the Greek words 'oxys' meaning 'acid' and 'genes' meaning 'forming'. Oxygen was first discovered by Swedish scientist Carl Wilhelm Scheele in 1772, but it was independently discovered by Joseph Priestley in 1774. Oxygen plays a vital role in sustaining life on Earth and is essential for various biological processes.
