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.
Reactive nitrogen ("Nr"), also known as fixed nitrogen [1], refers to all forms of nitrogen present in the environment except for molecular nitrogen (N 2 ). [ 2 ] While nitrogen is an essential element for life on Earth, molecular nitrogen is comparatively unreactive, and must be converted to other chemical forms via nitrogen fixation before it ...
Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air, or by mechanical means using gaseous air (pressurised reverse osmosis membrane or pressure swing adsorption). Nitrogen gas generators using membranes or pressure swing adsorption (PSA) are typically more cost and energy efficient than bulk-delivered ...
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.
In 1916, Gilbert N. Lewis formulated the octet rule, which concluded an octet of electrons in the outer shell was the most stable arrangement for any atom; this arrangement caused them to be unreactive with other elements since they did not require any more electrons to complete their outer shell.

The use of nitrogen hypoxia has been the subject of delays in Alabama that have focused not on whether it is inhumane, but logistical issues of how it would be administered.
Nitrogen is a colourless, odourless, and relatively inert diatomic gas with a density of 1.251 × 10 −3 g/cm 3 (marginally heavier than air). It condenses to a colourless liquid at −195.795 °C and freezes into an ice- or snow-like solid at −210.00 °C.
