Answer 2

Heya !!!

Here is your answer
=================

The atomic radius goes on increasing down a group, as atomic size increases down the group. This is because new shells are being added as we go down the group.

This increases the distance between the outermost electrons and the nucleus so that the atomic size increases in spite of the increase in nuclear charge.
