SUMMARY
The effective nuclear charge (Zeff) experienced by an electron in the M (n=3) shell of xenon (Z=54) is calculated using the formula Zeff = Z - total electrons in K and L shells. In this case, the total electrons in the K shell are 8 and in the L shell are 18, leading to Zeff = 54 - 26 = 28. This calculation is confirmed as correct, providing a definitive value for Zeff in xenon.
