Purified argon and nitrogen gases are most commonly used as inert gases due to their high natural abundance (78.2% N2, 1% Ar in air) and low relative cost.Unlike noble gases, an inert gas is not necessarily elemental and is often a compound gas. Like the noble gases the tendency for non-reactivity is due to the valence, the outermost electron shell, being complete in all the inert gases.[2] This is a tendency, not a rule, as noble gases and other "inert" gases can react to form compounds.Some name of inert gases are (1)Helium,(2)Radon,(3)Neon (4)Argon (5)XenonContents 1 Production 2 Applications 2.1 Inert gas systems on ships 2.2 Welding 2.3 Diving 3 See also 4 ReferencesProductionThe inert gases are obtained by fractional distillation of air, with the exception of helium which is separated from a few natural gas sources rich in this element,[3] through cryogenic distillation or membrane separation[4].

Production
The inert gases are obtained by fractional distillation of air, with the exception of helium which is separated from a few natural gas sources rich in this element,[3] through cryogenic distillation or membrane separation[4]. For specialized applications, purified inert gas may be produced by specialized generators on-site. They are often used aboard chemical tankers and product carriers (smaller vessels). Benchtop specialized generators are also available for laboratories.
Applications
Because of the non-reactive properties of inert gases they are often useful to prevent undesirable chemical reactions from taking place. Food is packed in inert gas to remove oxygen gas. This prevents bacteria from growing.[5] It also prevents chemical oxidation by oxygen in normal air. An example is the rancidification (caused by oxidation) of edible oils. In food packaging, inert gases are used as a passive preservative, in contrast to active preservatives like sodium benzoate (an antimicrobial) or BHT (an antioxidant).
Historical documents may also be stored under an inert gas to avoid degradation. For example, the original documents of the U.S. Constitution is stored under humidified argon. Helium was previously used, but it was less suitable because it diffuses out of the case more quickly than argon.[6]
Inert gases are often used in the chemical industry. In a chemical manufacturing plant, reactions can be conducted under inert gas to minimize fire hazards or unwanted reactions. In such plants and in oil refineries, transfer lines and vessels can be purged with inert gas as a fire and explosion prevention measure. At the bench scale, chemists perform experiments on air-sensitive compounds using air-free techniques developed to handle them under inert gas. Helium, Neon, Argon, Krypton, xenon, And Radon are Inert gases.
