Joseph Priestley is usually given priority in the discovery in 1774.
Oxygen was first discovered by Swedish pharmacist Carl Wilhelm Scheele. He had produced oxygen gas by heating mercuric oxide and various nitrates by about 1772. Scheele called the gas "fire air" because it was the only known supporter of combustion, and wrote an account of this discovery in a manuscript he titled Treatise on Air and Fire, which he sent to his publisher in 1775. However, that document was not published until 1777.
In the meantime, on August 1, 1774, an experiment conducted by the British clergyman Joseph Priestley focused sunlight on mercuric oxide (HgO) inside a glass tube, which liberated a gas he named "dephlogisticated air". He noted that candles burned brighter in the gas and that a mouse was more active and lived longer while breathing it. After breathing the gas himself, he wrote: "The feeling of it to my lungs was not sensibly different from that of common air, but I fancied that my breast felt peculiarly light and easy for some time afterwards." Priestley published his findings in 1775 in a paper titled "An Account of Further Discoveries in Air" which was included in the second volume of his book titled Experiments and Observations on Different Kinds of Air. Because he published his findings first, Priestley is usually given priority in the discovery.

Who was the first person who discovered oxygen?
The discovery of oxygen is credited to the Swedish chemist Carl Wilhelm Scheele in 1772. However, the discovery is often also attributed to Joseph Priestley, an English chemist, who independently isolated oxygen in 1774.
Was oxygen made discovered or was it found?
Oxygen was discovered by Carl Wilhelm Scheele in 1772 and independently by Joseph Priestley in 1774. The element had already existed in nature; its discovery involved recognizing it as a distinct substance and understanding its properties.
Who discovered that blood carries oxygen?
The discovery that blood carries oxygen was made by a French physiologist named Antoine Lavoisier in the 18th century. Lavoisier's experiments demonstrated that blood absorbs oxygen in the lungs and releases carbon dioxide, leading to our current understanding of how oxygen is transported in the body.
Who was search oxygen?
The scientist Joseph Priestley is often credited with discovering oxygen in 1774 through his experiments with heating mercuric oxide. However, the discovery of oxygen is also attributed to Carl Wilhelm Scheele and Antoine Lavoisier around the same time.
What evidence is there to prove phlogiston theory of burning was correct?
The phlogiston theory has been debunked by the discovery of oxygen. When materials burn, they combine with oxygen, not phlogiston as believed in the theory. The understanding of combustion and oxidation provided by oxygen led to the rejection of the phlogiston theory.
What was the date of discovery for oxygen?
1782
Scientists is credited with the discovery of oxygen?
Joseph Priestly
Who was the first person who discovered oxygen?
The discovery of oxygen is credited to the Swedish chemist Carl Wilhelm Scheele in 1772. However, the discovery is often also attributed to Joseph Priestley, an English chemist, who independently isolated oxygen in 1774.
What was Antonie Lavoisier discovery and the year?
Antoine Lavoisier is known for his discovery of the role of oxygen in combustion around 1777. He demonstrated that oxygen is necessary for combustion to occur and debunked the concept of phlogiston theory.
Who discovered that oxygen are necessary of burning?
Joseph Priestley is credited with this discovery.
Why did the discovery of oxygen overturn the phlogiston theory?
I don' t know
What is oxygens date of discovery?
Oxygen was discovered by Joseph Priestley and Carl Scheele in 1774.
Where are the oxygen sensors located on a 2001 land rover discovery II?
in the human heart
How can oxygen be efficient for space discovery?
Oxygen is used in the launch of space vehicles to make discoveries.
What law did Lavoisiers work establish?
He changed the science of chemistry from Quantitative to qualitative and is most noted for his discovery of the role that oxygen plays in combustion.
How do you use the word oxygen in a sentence?
The word is spelled oxygen. Humans breathe oxygen and release carbon dioxide. Plants use carbon dioxide and release oxygen.
In 1777 french scientist Antoine lavoiser made a discovery about the role of oxygen in the burning of matter?
a cat
