WebJun 9, 2024 · The key point to consider is the octet rule. Since nitrogen has 5 valence electrons, the most that it can "lose" while forming bonds in a molecule is 5, so its highest possible oxidation number is \(+5\). Alternatively, it could gain up to 3 electrons, and so its lowest (most negative) possible oxidation number is \(-3\).
