Atlas: nitrogen oxides

Nitrogen forms several oxides including NO, NO₂, N₂O, N₂O₃, N₂O₄, and N₂O₅. Their structures and properties differ substantially.

Not one substance

N₂O is nitrous oxide; NO is nitric oxide; NO₂ is nitrogen dioxide. NO and NO₂ feature in air-quality discussions, while N₂O has distinct climate and medical relevance.

Higher oxides

N₂O₃ and N₂O₅ connect to nitrous and nitric acid chemistry. NO₂ and N₂O₄ can exist in temperature-dependent equilibrium. Compound-specific references and safety data matter.

Fact capsuleThe family portrait has six formulas; none should be identified as “the brown one” alone.
