Who discovered oxygen gas for the first time?
Joseph Priestley
When Joseph Priestley discovered oxygen in 1774, he answered age-old questions of why and how things burn.
How did Scheele discovered oxygen?
The Discovery of Oxygen. Scheele produced oxygen by heating a variety of substances including mercuric oxide, as did Priestley. Scheele also obtained the gas by heating potassium nitrate, silver carbonate, manganese nitrate, and manganese oxide.
Why did Scheele call oxygen fire?
Oxygen was discovered by Swedish chemist Carl Wilhelm Scheele in 1772. He discovered that by heating mercuric oxide, a gas (later identified as oxygen) formed. Scheele called the gas “fire air” because it produced sparks as it came in contact with hot charcoal dust.

Which gas was discovered by Scheele?
Carl Wilhelm Scheele, Carl also spelled Karl, (born December 9, 1742, Stralsund, Pomerania [now in Germany]—died May 21, 1786, Köping, Sweden), German Swedish chemist who independently discovered oxygen, chlorine, and manganese.
What killed Carl Scheele?
Mercury poisoning
Carl Wilhelm Scheele/Cause of death
Cumulative exposure to arsenic, mercury, lead, their compounds and perhaps hydrofluoric acid which he had discovered, as well as other substances took their toll on Scheele, who died at the early age of 43, on 21 May 1786, at his home in Köping. Doctors said that he died of mercury poisoning.
How was chlorine discovered?
Chlorine was discovered in 1774 by Carl Wilhelm Scheele. He obtained it through the reaction of the mineral pyrolusite (manganese dioxide, MnO2) with hydrochloric acid (HCl, then known as muriatic acid). Sir Humphry Davy proposed and confirmed chlorine to be an element in 1810, and he also named the element.
Did Carl Wilhelm Scheele discover oxygen?
Carl Wilhelm Scheele (1742-1786) has an important place in the history of the discovery of respiratory gases because he was undoubtedly the first person to prepare oxygen and describe some of its properties. Arguably he discovered seven new elements and many other compounds.

Krypton/Discoverers
In 1898, British chemists William Ramsay and Morris Travers discovered krypton as the residue of evaporating almost all of the other components of liquid air. For his work in the discovery of several inert gases, Ramsay was awarded the Nobel Prize in Chemistry in 1904.
