The total distance that exists between the nucleus and the valence shell electrons of an atom is known to be the atomic size or atomic radius of that atom. According to the periodic table, the atomic size increases while going down the group and decreases while moving left to right in the period.

The ionic radius also increases while going down the group and decreases while moving left to right in the period.
