Question

Who Discovered Oxygen​

Answer 1

Answer:

Oxygen was "discovered" by a number of scientists over a fairly brief time period. First discovery is normally credited to the Swedish scientist Carl Wilhelm Scheele in 1772. He called his discovery "fire-air" because it supported combustion.

Unfortunately (for him), Scheele's findings weren't published until 1777. In the interim, British clergyman and chemist Joseph Priestley, in 1774, discovered oxygen independently. He called it "dephlogisticated air."

Answer 2

Answer:

Joseph Priestley discovered oxygen in 1774, he answered age-old questions of why and how things burn. An Englishman by birth, Priestley was deeply involved in politics and religion, as well as science. When his vocal support for the American and French revolutions made remaining in his homeland dangerous, Priestley left England in 1794 and continued his work in America until his death.
