An inert gas is a type of gas that doesn’t experience chemical reactions under any set of specific conditions. Unlike the noble gases, an inert gas isn’t necessarily elemental, and is often a compound gas.This tendency toward non-reactivity exists due to the valence, the outermost electron shell, being occupied with the maximum amount of possible electrons, making them stable. Keep in mind, though, that this a tendency, not a steadfast rule, since noble and other inert gases can sometimes experience reactions that result in forming compounds. The 6 noble gases can be located in “group 18″ of the periodic table.
Both Helium and Neon are the only two genuine elemental inert gases of the 6 inert gases on the periodic table, due to the fact that they don’t form any currently known genuine chemical compounds, unlike the heavier noble gases, which are Argon, Krypton, Radon, and Xenon.
What Applications Do Inert Gases Serve?
Marine Applications – In marine applications, inert gas are utilized for their low oxygen content. Inert gases are utilized to fill empty spaces in and around gas tanks to safeguard against any explosions.
Deep Sea Diving – An inert gas is part of the breathing mixture that comprises the air contained in a diving tank. This mixture isn’t metabolically active and is employed in the gas mixture to dilute it. The most typical inert gas used in diving tanks is helium, due to its affordability.
Welding – In GTAW (gas tungsten arc welding), inert gas is employed to safeguard the tungsten from being contaminated and also serves to shield the liquid metal that the arc produces as a result of the airborne reactive gases, which can create a porous portion of a solid welding puddle. Inert gases are additionally utilized in GMAW to weld non-ferrous metals.
