Oxygen's+History

Oxygen was discovered by Joseph Priestly in 1774. He found the oxygen while experimenting with mercuric oxide, which he found a gas in a glass tube. He discovered that his candle was burning brighter in a gas, which he named 'dephlogisticated air'. Priestly published that he found oxygen in 1775 in a newspaper, but before, a Swedish pharmacist, Carl Scheele already made deoxygenate gas in 1772, by heating a mercuric oxide. He wrote a book about what he dixcovered, but that book was published in 1777, so it's told that Priestly discovered the oxygen before Scheele. The name 'oxygen' came from Antoin Lavoisier, who had an experiment with oxgen in 1777. This is a portrait of Joseph Priestly This is Antoine Lavoisier This is a portrait of Carl Scheele
