So right here we had a plus one and here we have a minus one on the end. That means it will have one more electron than a dot in its neutral state. So instead of having three electrons in its two p it's going to have four electrons in its two p orbital. 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.
