1. Homework Statement

In xenon (Z = 54), what is the effective charge Zeff experienced by an electron in the M (n=3) shell?


2. Homework Equations

Zeff = Z - total electrons in K and L shells

3. The Attempt at a Solution

I think total electrons in K shell are 8 and in L shell are 18
then Zeff = 54-26 = 28

but I got wrong..
