Question

Why are noble gases larger than the halogens?

Answer 1

noble gases have comparatively higher atomic size than corresponding halogens because of the reason that vander waal's radii (present in noble gases) is much larger than ionic and covalent radii (present in other elements).

Answer 2

Answer

Noble gas larger because it has vander waal radii .

Explanation

Noble gases are larger then halogen because the radii of noble gases measured by the help of vander waal radius which comparatively larger than the other radius like covalent radius.

Halogens have Covalent radii which is smaller then the vander waal radii. So the atomic size and atomic radius of noble gases are larger than the halogen .

Because of the vander waal radius noble gases are unable to form molecule and they are known as inert gas .

As the noble gases are stable because of the fully filled orbitals and having the stable electronic configuration, which make them inert and unable to form bond with others.
