Mark the correct order of s, p, d and f orbitals with respect to their shielding effect
The electrons in the valence shell experience an attractive force from the nucleus and a
repulsive force from the electrons in the inner shells. This repulsive force felt by the
valence shell electrons from the electrons present in the inner shells is called the
shielding effect.
Shielding effect of shells closer to nucleus is higher. Therefore, the correct order of
shielding effect is
Hence option 1 is correct.
