Web4 jan. 2024 · 18 e⁻ = 9 pairs or electrons. The two simple bonds + the double bond represent 4 electron pairs. So, there are still 5 electron pairs to place. One of the O forms two single bonds, so it already has 2 pairs of electrons. It needs two more pairs to get the 8e⁻. So 4 electrons are placed arround this O. The other O forms a double bond with N.
