shielding effect

Question

The shielding effect on valence electrons is maximum when the inner shells contain:

RankGuru · Accepted Answer

**Shielding (Screening) Effect** is the reduction in nuclear attraction on valence electrons due to the presence of inner shell electrons.
- The effectiveness of shielding depends on the shape of the orbital. Orbitals closer to the nucleus screen more effectively.
- **Order of Shielding**: $s > p > d > f$.
- **$s$-electrons** have the highest penetration power and spherical symmetry, providing the most 'shadow' or protection from the nuclear charge for electrons in outer shells.
