" This compound makes up about 80% of the atmosphere.
This is the largest homonuclear diatomic molecule with a pi-u molecular orbital at a lower energy than a sigma-g orbital. Along with water, carbon dioxide, and sulfur dioxide, it has a zero enthalpy of combustion. Old airbags produced this compound from sodium azide. It is isoelectronic to carbon monoxide. An iron catalyst is used to break down this compound at very high pressures in the Haber process because it is so unreactive. In nature, the conversion of it to ammonia is called "fixation." This compound makes up about 80% of the atmosphere. For 10 points, name this diatomic gas consisting of element number 7.
