What is special about argon?
Argon provides an inert atmosphere in which welded metals will not oxidise. Argon is a colourless, odourless gas that is totally inert to other substances. Argon is often used when an inert atmosphere is needed. It is used in this way for the production of titanium and other reactive elements.
Who was Argon discovered by?

How is argon isolated?
Argon is isolated from air by fractionation, most commonly by cryogenic fractional distillation, a process that also produces purified nitrogen, oxygen, neon, krypton and xenon.
How is argon mined?
Argon is industrially extracted from liquid air in a cryogenic air separation unit by means of fractional distillation. When nitrogen gas present in the atmosphere is heated using hot calcium or magnesium, a nitride is formed leaving behind small amount of argon as an impurity.
Where was argon found?
Where is argon found on Earth? Argon is the most abundant of the noble gases in the Earth’s atmosphere. It constitutes nearly 1% (0.94%) of the volume of air making it the third most abundant element in air after nitrogen and oxygen. Argon is also found in small traces in the Earth’s crust and ocean waters.
