Question

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 ______.

Options

• s > p > d > f

• f > d > p > s

• p < d < s > f

• f > p > s > d

Answer 1

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 s > p > d > f.

Explanation:

The screening effect of the orbitals follows the order of s > p > d > f as screening effect decreases from s-orbital to f-orbital in an atom on account of shape of the orbital.
