Problem

The effective nuclear charge for an atom is less than the actual nuclear charge due

a. shielding.

b. penetration.

c. paramagnetism.

d. electron-pair repulsion.

e. relativity.

Solution

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.
