Q. Assertion: Shielding effect increases as we go down the group.
Reason : More is the number of electrons in the penultimate shell, more is the shielding.

Classification of Elements and Periodicity in Properties

Solution:

Complete electron shells shield the nuclear charge very effectively. On moving down the group, the number of complete electron shells increases. Also, the nuclear core is farther removed from the valence electrons.
