Now, once again, we draw out the full atomic orbital picture for our oxygen. So two go into the one S, which we did not draw because it's within our two S. So two go into the two S.
So here's our sphere to go inside the two S, two go to the two PX. So two go into the two PX. One goes into two PY. So one goes into this one, and finally, one goes into the two PZ. So once again, this took a lot of time.
