Oct 17, 2018 · Argon was discovered by Sir William Ramsay and Lord Rayleigh in 1894 (Scotland). Prior to the discovery, Henry Cavendish (1785) suspected some unreactive gas occurred in air. Ramsay and Rayleigh isolated argon by removing the nitrogen, oxygen, water, and carbon dioxide.
Argon is a heavier gas than helium, so if a balloon is filled with argon, it would fall to the ground. History [ change | change source ] Argon was first removed from air in 1894 by Lord Rayleigh and Sir William Ramsay at University College London by removing oxygen , carbon dioxide , water , and nitrogen from a sample of clean air .
Explore the comprehensive guide on Argon, the versatile noble gas with wide-ranging applications. Discover its history, properties, uses in industries like welding, metal production, and medicine, as well as its safety guidelines.
Argon is a colourless and odourless gas present to a very small extent in the atmosphere. Argon is very inert (indeed it is referred to as one of the noble gases) and is not known to form true chemical compounds.
