So two going to the one S, two going to the two S, and four going to the two P. H is once again neutral. It has one electron in the one s. So we have two h atoms. So two times one, we have two electrons balance electrons coming from h and two plus four six electrons coming from n.
So altogether, once again we have eight balance electrons. So once again we begin our drawing by writing or drawing n in the middle of the central atom and h is adjacent to it. So we connect our atoms, and now we are left with four balance electrons. Because we begin with eight balance electrons.
