Among the following pairs of orbitals which orbital will experience the larger effective nuclear charge? (i) 2s and 3s, (ii) 4d and 4f, (iii) 3d and 3p.

(i)
Answer

2s

(ii)
Answer

4d

(iii)
Answer

3p

Explanation

Effective nuclear charge experienced by an electron depends on its distance from the nucleus. Orbitals closer to the nucleus experience a larger effective nuclear charge. For orbitals with the same principal quantum number, the one with a lower azimuthal quantum number penetrates closer to the nucleus.
