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.
