Nitrogen, the seventh element in the periodic table, has an atomic number of 7, indicating the presence of seven electrons in its neutral state. The electronic configuration of Nitrogen can be represented as 1s² 2s² 2p³, which means that it has two electrons in the 1s orbital, two electrons in the 2s orbital, and three electrons in the 2p orbital.
The first shell, 1s, can hold a maximum of two electrons, while the second shell, 2s and 2p, can hold a maximum of eight electrons. Nitrogen, therefore, has a half-filled 2p orbital, which makes it more stable compared to a completely filled 2s orbital.

Another pathway for the formation of NO is through the oxidation of nitric acid (HNO3) by reducing agents such as metallic fuels, which produces nitrogen dioxide (NO2) that can subsequently react with other species to form NO.
Discussion on how Nitrogen and Oxygen contribute their valence electrons
During the formation of Nitric Oxide, both the nitrogen and oxygen atoms contribute their valence electrons to form covalent bonds. Nitrogen, with an atomic number of 7, has an electron configuration of 1s2 2s2 2p3. In the formation of NO, one of the nitrogen atom’s unpaired electrons pairs up with an unpaired electron from oxygen, resulting in the sharing of a pair of electrons and the formation of a sigma bond (σ). This shared pair of electrons contributes to the valence shell of both atoms simultaneously.
Similarly, oxygen, with an atomic number of 8, has an electron configuration of 1s2 2s2 2p4. Oxygen shares one of its unpaired electrons with nitrogen to form the sigma bond and the other two unpaired electrons participate in the formation of a lone pair on the oxygen atom.
