@my2cts Hello I added a sketch to better describe my question.

comment Why does the nuclear charge remain the same in Moseley's law?
@MaxW Sorry for the countless questions but I still don't quite get what you mean. If this hole is outside the interested electrons, then there shouldn't be any effect on it according to the Slater's rules? Is there any website/link/wikipedia page that will help me understand more about this "hole" acting as a perturbation of Slater's rules? My major isn't about physics and I feel like my professor merely touched the very surface of this topic.

@MaxW What is the reason behind thinking of σ as for the shielding of the most bound electron?

@MaxW So my understanding now is that the Moseley's law is empirical. The $\sigma$ value comes from the experiment results. It can only be used to describe certain de-excitation of atoms. The part I am confused about is that my professor said the $\sigma$ value in Moseley's law theoretically should be the no. of electrons under the jumping electron. Just like the example I gave in the post. Is he correct?

I still don't get it. Rydberg formula is used for atoms that have a similar structure to hydrogen (only 1 electron). Therefore it makes sense that Z is squared as the electron is pulled by the same amount of charges (Z) no matter the level. But in Moseley's law, it applies to atoms with more electrons. Due to the shielding effect, the sigma value should be different for different level of the electron. So how is the (Z-sigma) squared in the Moseley's law?
