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).
Corner Gas is a Canadian television sitcom created by Brent Butt.The series ran for six seasons from 2004 to 2009. Reruns still air on CTV, CTV2, CTV Comedy Channel, Much, MTV, E! and are streaming on Crave and Amazon Prime.
Argon (symbol Ar) is the third element in group 18, the noble gases. Argon is the third most common gas in the Earth's atmosphere, at 0.93%, making it more common than carbon dioxide. Nearly all of this argon is radiogenic argon-40 derived from the decay of potassium-40 in the Earth's crust.

Jerbal Argon is a recurring character in the Artemis Fowl series, first introduced in the inaugural book. Initially depicted as an observer, he later emerges as the proprietor of a health clinic. In "Artemis Fowl: The Opal Deception," Argon tends to Opal Koboi, a prominent patient in a self-induced coma, whose presence ensures financial support ...
Argon is the most common shielding gas, widely used as the base for the more specialized gas mixes. [ 5 ] Carbon dioxide is the least expensive shielding gas, providing deep penetration, however it negatively affects the stability of the arc and enhances the molten metal's tendency to create droplets (spatter). [ 6 ]
The term inert gas is context-dependent because several of the inert gases, including nitrogen and carbon dioxide, can be made to react under certain conditions. [1] [2] Purified argon gas is the most commonly used inert gas due to its high natural abundance (78.3% N 2, 1% Ar in air) [3] and low relative cost.
This molecule may occur in the upper atmosphere. Experimentally the molecule is made from a low-pressure argon gas with 0.1% carbon dioxide, irradiated by a 150 V electron beam. Argon is ionized, and can transfer the charge to a carbon dioxide molecule. [35] The dissociation energy of ArCO + 2 is 0.26 eV. [35] ArCO + 2 + CO 2 → Ar + CO 2 ·CO +
