So two going to the one s, two going to the two s, and two going to the two p. H still has that one electron in the one s because it's neutral. Now, notice, however, now we have four h atoms. And that means when we're counting our balanced electrons, we have not one electron from h, but four electrons from h. So four times one. So we have four electrons coming from h, and two plus two four electrons coming from our boron. So altogether, we have eight balanced electrons. So once again, we place our b in the middle, our central atom, and we place our h atoms around our b atom.
