Nitrogen oxide

Nitrogen has five different oxides:

• Nitric oxide (NO)
• Nitrous oxide (N₂O)
• Nitrogen dioxide (NO₂)
• Dinitrogen trioxide (N₂O₃)
• Dinitrogen pentoxide (N₂O₅)

The term nitrogen oxide is imprecice and can be used to refer to any of these or to a mixture of them. A mixture is often formed in chemical reactions that produce nitrogen oxides, with the proportions depending on the specific reaction and the conditions it is performed in.

See the articles for these oxides for details on their properties.
