When was the oxygen discovered?

Answer 1

i am not sure but i do know who discovered it...... Carl Wilhelm Scheele in 1772 but did not publish it until 1777 or 1778 another person named Joseph Priestly discovered it in 1774 and published it in 1775 and takes more credit on oxygen's discovery.

Answer 2

Oxygen was discovered for the first time by a Swedish Chemist, Carl Wilhelm Scheele, in 1772. Joseph Priestly, an English chemist, independently, discovered oxygen in 1774 and published his findings the same year, three years before Scheele published. Antoine Lavoisier, a French chemist, also discovered oxygen in 1775, was the first to recognize it as an element, and coined its name "oxygen" - which comes from a Greek word that means "acid-former".

Answer 3

Joseph Priestley discovered oxygen in 1775.

Joseph had started experimenting with air in 1774, and he first discovered a 'new air' which he called vitriolic acid air in January 1775, which is commonly known as sulphur dioxide (SO2).

In March 1775, he discovered 'dephlogisticated air,' which was his name for oxygen (O2). He discovered it by focusing the sun's rays on some mercuric oxide. The substance he produced was oxygen, which he tested first on mice. The mice survived for a long time in the oxygen. He also tested it on himself afterwards.

Oxygen on its own, he discovered, was 5 or 6 times better than normal air that we breathe, as most of what we breathe is not useful to our lungs (e.g. nitrogen [N2 - 78%], argon [Ar - 0.93%] and carbon dioxide [CO2 - 0.03%]) goes back out again. Only the oxygen [O2 - 20.95%] is used.
