$s > p > d > f$

Vedclass · Answer

(A) The screening effect (or shielding effect) is the reduction in the effective nuclear charge on an electron due to the presence of other electrons in the inner shells or the same shell. For a given shell,the $s$-orbital is closest to the nucleus and has the highest electron density near the nucleus,making it the most effective at shielding outer electrons. The order of penetration power and screening ability is $s > p > d > f$. This is because $s$-orbitals are more spherical and closer to the nucleus,while $f$-orbitals are more diffused and further away,providing the least shielding. Therefore,the correct order of the screening effect is $s > p > d > f$. Hence,the correct option is $A$.

The order of screening effect among $s, p, d$ and $f$-orbitals of a given shell of an atom on its outer shell electrons is
