Effective Nuclear Charge vs. the Energy of a Shell

[Karishma_1G]

Hi, I was wondering what the difference/relationship was between the effective nuclear charge experienced by an electron and the energies of the different shells (E_n) that the electrons are in (n=1, n=2, etc.). Thank you in advance!

I think they have somewhat of a proportionate relationship. The higher n is, the lower the effective energy. Of course it also depends on how filled the last shell is and how many shells in total the atom has.
