N in N₂O

N is +1 in nitrous oxide.

Oxidation number

Type a formula or an ion: K2Cr2O7, Cr2O7 2-, MnO4-, NH4+ or K4[Fe(CN)6]. Put a known ion in brackets when two elements are unknown. Pick an element to solve for it.

N+1

  1. Oxygen is −2 in most compounds.
  2. The oxidation numbers add up to the charge, 0: (−2) + 2x = 0.
  3. 2x = +2, so x = +1.
