However, since you did not specify, the assumption is that you. In helium, would this still be true? Helium atoms have two protons, two neutrons, and two electrons.

In helium, would this still be true?

The next atom is helium. We must expect its remaining electron to act like a hydrogen electron. When electrons fill the energy levels, it fills principal energy levels, sublevels, atomic orbitals from lowest energy first. And the last term of eq.1 is repulsive coulomb interaction between two electrons.
