Atomic size increases from top to bottom.

Explanation:

As we move from top to bottom in periodic table , the shells keep increasing by 1 , each period.

Electrons remain constant in a particular group , that's why nucleus is not affected by electron attraction.

Atomic size is determined by atomic radius, which increases when distance between nucleus and outermost shell increases.
