a. Compare the size of `Cl, and Cl^(ɵ)` ion.
b. the radii of `Ar` is greater than the radii of chlorine. Explain.

Text Solution

Verified by Experts

In chlorine, the radii means the atomic or covalent radii which are actually half the inter-nuclear distance between 2 atoms whereas in Argon the radii means the van der Waals radii as Argon is not a diatomic molecule. van der Waals radii are actually half the distance between adjacent molecules. So van der Waals radil being larger than atomic radil, Argon has got a larger radii than chlorine
