Nitrogen Dioxide Formula

Nitrogen Dioxide formula is explained in this article. It is an extremely poisonous gas. It can function as an inhibitor. It is a pollutant which absorbs UV light and does not allow it to come to the earth’s surface. This chemical compound is paramagnetic consisting of two oxygen atoms connected to a nitrogen atom. The bond angle 134.4° whereas the distance between nitrogen and oxygen is 119.7 pm. The chemical or molecular formula of Nitrogen Dioxide is NO2.

In its gaseous state, it appears as a reddish-brown gas. In its liquid state, it appears as a yellowish-brown coloured compound. It has a pungent to acrid smell. It is toxic when inhaled and absorbed through the skin. Non-combustible, but enhances the burning of combustible materials.
