how do you expect the size of the atoms to change as you go from neon to argon to krypton

As they are all Noble Gases, they are all in the same family. However, as you go further down the list of Noble Gases, the period number increases. The period number shows the number of energy levels. Hence, an increase in energy levels.

The size of the atoms (atomic radius) would increase down the group from neon to argon to krypton.

What is atomic radius?

Atomic radius can be defined as a measure of the size (distance) of the atom of a chemical element, typically from the nucleus to its valence electrons.

The trends of atomic radius.

Generally, the atomic radius of a chemical element decreases across the periodic table, from alkali metals (group 1 elements) to noble gases (group 8 elements). Also, the atomic radius of a chemical element increases down each group of the periodic table, typically from top to bottom (column).

In this context, the size of the atoms (atomic radius) would increase down the group from neon to argon to krypton.
