Argon is a chemical element; it has symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas.[10] Argon is the third most abundant gas in Earth's atmosphere, at 0.934% (9340 ppmv). It is more than twice as abundant as water vapor (which averages about 4000 ppmv, but varies greatly), 23 times as abundant as carbon dioxide (400 ppmv), and more than 500 times as abundant as neon (18 ppmv). Argon is the most abundant noble gas in Earth's crust, comprising 0.00015% of the crust.    

Argon Application

Uses: A rare gas. Used as a shielding gas for arc welding (cutting) stainless steel, magnesium, aluminum, and other alloys. Also used in the smelting of steel, aluminum, titanium, and zirconium. Argon emits a purple glow when discharged, and is also used in lighting technology and filling fluorescent lamps, photoelectric tubes, lighting tubes, etc.
In the brewing process, it is a filler in beer barrels. It can replace oxygen to prevent the raw materials in the beer barrels from being oxidized into acetic acid.
It is also used in heat treatment processes to replace nitrogen and ammonia, and the effect is even better than nitrogen and ammonia. When stainless steel is heat treated, argon is used to protect the bending effect, which is better and less likely to break.
