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

Question

Philoid · Accepted Answer

when the electron is in the same shell then the order of the screening effect is s > p > d > f.

shielding effect is the decrease in effective nuclear charge on the electron cloud due to the inner shells which results in an easy removal of the valence shell electrons as nuclear attraction on them decreases.
