(ii) 4d and 4f,

(iii) 3d and 3p

##### Solution :-

The nuclear charge can be defined as the net positive charge that acts on an electron in the orbital of an atom that has more than 1 electrons. It is inversely proportional to the distance between the orbital and the nucleus.

(i) Electrons that reside in the 2s orbital are closer to the nucleus than those residing in the 3s orbital and will, therefore, experience greater nuclear charge.

(ii) 4d orbital is closer to the nucleus than 4f orbital and will, therefore, experience greater nuclear charge.

(iii) 3p will experience greater nuclear charge (since it is closer to the nucleus than the 3f orbital).
