Homework Statement
In xenon (Z = 54), what is the effective charge Zeff experienced by an electron in the M (n=3) shell?
Homework Equations
Zeff = Z - total electrons in K and L shells
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..
please help me..
