Argon gas is one of the noble gas elements found in the earth's atmosphere. This element was discovered by Sir William Ramsay and Lord Rayleigh in 1894. Argon gas is included in the noble gas group because it is very stable and does not react with other elements except under extreme conditions.
Argon gas is a colorless, odorless and non-toxic gas. This gas has a specific gravity of about 1.38 times that of air, so it is easier to collect at the bottom of the chamber. Argon gas is non-flammable and does not easily react with other substances, so it is often used in industry and various other fields.
