Argon is a colorless, odorless inert gas composed of argon atoms. At room temperature, it does not undergo chemical reactions with any other substances; furthermore, it remains insoluble in liquid metals even at high temperatures, thereby demonstrating its superior advantages particularly during the welding of non-ferrous metals.
1. Physical Properties
Argon is a colorless and odorless gas with a density approximately 1.4 times that of air and 10 times that of helium. It is the most abundant noble gas found in the atmosphere. It is slightly soluble in water at room temperature and emits a bluish-purple glow when subjected to an electric current.
2. Chemical Properties
Argon is a quintessential inert gas. Argon atoms are situated in Group 0 of the periodic table, a group in which all elemental forms consist of rare inert gases. Its chemical properties are exceptionally stable; it is non-toxic and typically does not form chemical compounds with other elements.
