Expert Answer
Atomic radii in a modern periodic table decreases from left to right in a period So inert gases have smallest radii.
So Assertion is false.
Zeff increases across a period from left to right because of due to increasing nuclear charge with no accompanying increase in shielding effect.
So Zeff of inert gases is not minimum.
Hene, both assertion and reason are false
