Remember, there are three p orbitals. And what Hungry tells us is that before we add two electrons into an orbital, first all the orbitals must be filled with at least one electron. And that's exactly why we first add one electron to the PX orbital. Then we add the second electron to the PY orbital. And then we're adding the third electron into the PV orbital to give us a total of two plus two, four plus three seven electrons. This nitrogen has seven protons and seven electrons in its neutral state.
