| nitrogen dioxide |
A brown gas, formula NO 2 , found at all levels in the atmosphere. In the troposphere it photodissociates to give free oxygen atoms, which then form ozone, and is thus a key player in local and regional air pollution events. In the stratosphere it participates in catalytic ozone destruction cycles, but also forms stable nitrate reservoir species that ameliorate ozone loss.

| nitrogen |
(Symbol N.) A colorless, tasteless, odorless gaseous element, atomic number 7, atomic weight 14.007. It is the most abundant constituent of the atmosphere, amounting to 78.09% by volume of dry air. The molecular formula for nitrogen gas is N 2 ; its molecular weight is 28.016. Nitrogen enters the atmosphere from volcanoes and from the decay of organic matter. It is removed from the atmosphere by certain natural nitrogen-fixing bacteria for use in plant life processes. ...
