  • 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: (i) s >p >d >f (ii) f> d > p> s (iii) p< d < s > f (iv) f> p > s> d

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:

 (i) s >p >d >f

(ii) f> d > p> s 

(iii) p< d < s > f 

(iv) f> p > s> d

Answers (1)

The answer is the option (i) s >p >d >f

Explanation: The valence electrons experience a shielding or screening effect from the nucleus because of the intervening core electrons, wherein the effective nuclear charge experienced by a valence electron in an atom will be less than the actual charge on the nucleus. Like the 2s electron in lithium is shielded from the nucleus by the inner core of 1s electrons.
