Problem: Which will experience the greater effective nuclear charge, the electrons in the n = 3 shell in Ar or the n = 3 shell in Kr?

FREE Expert Solution

We’re being asked to whether electrons in the n = 3 of Ar or Kr experience greater effective nuclear charge (Zeff).


Recall that the effective nuclear charge is the force exerted by the nucleus onto an electron. Electrons that are further away from the nucleus have a lower effective nuclear charge. This means the orbital that experiences the greatest Zeff is closest to the nucleus.
