Oxygen Gas

Submitted by • August 15, 2016

Oxygen is one of the abundantly available gases in air. It makes about 21% of atmosphere by volume. It is important to all the life on earth. It was discovered by a Swedish chemist Scheele in 1772 by heating red oxide of mercury and by Priestley of England in 1774. Antony Lavoisier of France studied its properties and named as ‘Oxygen’ in 1776. The credit of discovery goes to Joseph Priestley because his papers were published earlier.
