How gases were discovered?

Answer 1

It was discovered in 1894 and it was Argon.
In 1785 Henry Cavendish, an English chemist and physicist, found that air contains a small proportion (slightly less than 1 percent) of a substance that is chemically less active than nitrogen. A century later Lord Rayleigh, an English physicist, isolated from the air a gas that he thought was pure nitrogen, but he found that it was denser than nitrogen that had been prepared by liberating it from its compounds. He reasoned that his aerial nitrogen must contain a small amount of a denser gas. In 1894, Sir William Ramsay, a Scottish chemist, collaborated with Rayleigh in isolating this gas, which proved to be a new element---argon.

Answer 2

1800 because people were wondering why its cold

Answer 3

The 'discovery' of Oxygen is, still, one of the most hotly debated questions of the Golden Age of Natural Philosophy. The four leading claimants are as follows;

• Michał Sędziwój of Warsaw, a Polish alchemist and natural philosopher in the late sixteenth century (c.1592). Sędziwój realized that air is a mixture of substances, one of which (later called oxygen) is a life-giving substance. He correctly equated this "elixir of life" with the gas given off by heating niter (or saltpeter, the mineral form of potassium nitrate), driving off the nascent oxygen. This very effective method of extracting oxygen is still demonstrated in elementary chemistry labs every year.
• Oxygen was rediscovered by the Swedish pharmacist Carl Wilhelm Scheele sometime before 1773, but his finding was not published until after the independent rediscovery by Joseph Priestley.
• Joseph Priestly isolated and identified oxygen on August 1, 1774. Priestley published his discovery in 1775, and Scheele, in 1777; consequently, Priestley is usually given the credit for discovering oxygen.
• Antoine Laurent Lavoisier, working separately but concurrently with Scheele and Priestley, named the gas "oxygen." from two Greek words-οξυς (oxys), meaning acid or sharp, and γεινομαι (geinomai), meaning to engender-based on the (then and incorrect) belief that all acids contain oxygen and are formed from oxygen. Since then, the definition of an acid has been revised so that oxygen is not necessarily part of the molecular structure of every acid.

Answer 4

Oxygen, O Carl Wilhelm Scheele Joseph Priestley 1771 1774 Nitrogen, N Daniel Rutherford Henry Cavendish, Joseph Priestley Carl Wilhelm Scheele 1772 1772 1772 Argon, Ar William Ramsay, John William Strutt- lord Rayleigh 1894 The minor noble gas are: Helium, Neon, Krypton, Xenon, Radon

Answer 5

The term was first used by Hugo Erdmann in 1898. Although these elements were discovered at different times (He, Ne, Ar, Kr, Xe, and Rn) they are all noble gases. One way Ramsay used to find the noble gases was through fractional distillation. It was 1898 when he discovered the elements krypton, neon, and xenon.

Answer 6

who discovered the different gases in the air and when

Answer 7

A lot of people discovered gases. If you meant oxygen, it was Joseph Priestley in 1774.
