N2O4 has a Lewis dot structure that begins with a pair of N atoms in the center joined by a single bond. Posted on 3rd November 2020 by . At 150 °C, NO2 decomposes with release of oxygen via an endothermic process (ΔH = 14 kJ/mol): As suggested by the weakness of the N–O bond, NO2 is a good oxidizer. Unlike NO 2, N 2 O 4 is diamagnetic since it has no unpaired electrons. The idea of paired electrons is for bonding. In NO2+ ion, Oxygen is more electronegative than nitrogen atoms. Create . With N 2 O 4 you'll need to form two double bonds between the two Nitrogen atoms and two Oxygen atoms to fill the octets with the available 34 valence electrons. Nitrogen is located in period 2, group 15 of the periodic table, which tells you that it has 5 valence electrons. Barbara. Solution: 0 0.
