Nitrogen oxide

Nitrogen oxide may refer to a binary compound of oxygen and nitrogen, or a mixture of such compounds:

Charge-neutral

• Nitric oxide (NO), nitrogen(II) oxide, or nitrogen monoxide
• Nitrogen dioxide (Template:Chem2), nitrogen(IV) oxide
• Nitrogen trioxide (Template:Chem2), or nitrate radical
• Nitrous oxide (Template:Chem2), nitrogen(0,II) oxide
• Dinitrogen dioxide (Template:Chem2), nitrogen(II) oxide dimer
• Dinitrogen trioxide (Template:Chem2), nitrogen(II,IV) oxide
• Dinitrogen tetroxide (Template:Chem2), nitrogen(IV) oxide dimer
• Dinitrogen pentoxide (Template:Chem2), nitrogen(V) oxide, or nitronium nitrate Template:Chem2
• Nitrosyl azide (Template:Chem2), nitrogen(−I,0,I,II) oxide
• Nitryl azide (Template:Chem2)
• Oxatetrazole (Template:Chem2)
• Trinitramide (Template:Chem2 or Template:Chem2), nitrogen(0,IV) oxide

Atmospheric sciences

In atmospheric chemistry:

• [[NOx|Template:Chem2]] (or NOx) refers to the sum of NO and [[nitrogen dioxide|Template:Chem2]].
• [[NOy|Template:Chem2]] (or NOy) refers to the sum of Template:Chem2 and all oxidized atmospheric odd-nitrogen species (e.g. the sum of Template:Chem2, [[Nitric acid|Template:Chem2]], [[Nitrous acid|Template:Chem2]], etc.)
• Template:Chem2 (or NOz) = Template:Chem2 − Template:Chem2

• Mixed Oxides of Nitrogen ("MON"): solutions of nitric oxide in dinitrogen tetroxide/nitrogen dioxide.

Stability

Due to relatively weak N–O bonding, all nitrogen oxides are unstable with respect to Template:Chem2 and Template:Chem2, which is the principle behind the catalytic converter, and prevents the oxygen and nitrogen in the atmosphere from combusting.
