Question
Why do noble gases have comparatively large atomic sizes?
Solution
Noble gas are stable so they cannot form molecules In case noble gas from molecule the force of attraction that acting is vander waal force.
On other hand, other element form covalent bond and it is well known that vander waal radii is larger than covalent radii. Thus noble gases have comparatively large atomic sizes.
