On moving along the period , the atomic radii decreases

Text Solution

Verified by Experts

The correct Answer is:
F
From halogens to noble gases atomic radii increases as amongst noble gas atoms, it is van der waals forces of attraction which are holding them together .Hence,atomic radii of noble gases is large than corresponding halogon.
