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. Unlike noble gases , an inert gas is not necessarily elemental and is often a compound gas.
The term inert may also be applied in a relative sense. For example, molecular nitrogen is an inert gas under ordinary conditions, existing as diatomic molecules, N 2. The presence of a strong triple covalent bond in the N 2 molecule renders it unreactive under normal circumstances.
Natural gas burning on a gas stove Burning of natural gas coming out of the ground. Natural gas (also called fossil gas, methane gas, or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) [1] in addition to various smaller amounts of other higher alkanes.
The noble gases (historically the inert gases, ... helium is extracted by fractional distillation from natural gas, which can contain up to 7% helium. [80]
Because an inert purge gas is used, the purge procedure may (erroneously) be referred to as inerting in everyday language. This confusion may lead to dangerous situations. Carbon dioxide is a safe inert gas for purging. Carbon dioxide is an unsafe inert gas for inerting, as it may ignite the vapors and result in an explosion. [2]
Cylinders containing argon gas for use in extinguishing fire without damaging server equipment. Argon has several desirable properties: Argon is a chemically inert gas. Argon is the cheapest alternative when nitrogen is not sufficiently inert. Argon has low thermal conductivity.

This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
