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:
1 f > p > s > d
2 p < d < s < f
3 f > d > p >s
4 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.

Assertion : Shielding effect increases as we go down the group. Reason : More is the number of electrons in the penultimate shell, more is shielding.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
The decrease in the effective nuclear charge on the valence electrons due to the electrons in the penultimate shell is called shielding effect. This effect increases as the number of penultimate electrons increases. So option (1) is correct.
