So our overall energy of our system increases as the electron moves away from our nucleus. And that's exactly why placing electrons further away from our nucleus will increase the energy of our system. That's exactly why nature tends to place electrons as close to our atom, as close to our nucleus as possible. Because placing it further away increases the energy of our system. And nature tends to take the lowest energy state. So that's exactly why when we look at the principal quantum numbers as our principal quantum numbers increase as we go from n equals one to n equals two to n equals three, or from Orbital S P to D. Our energy will increase as we go down this table.
