In respect to the electron in atom as electron density decrease in the atom the ionic radii decrease.

When the negative charge increases that means the number of outer most electrons are also increases that cause more repulsion and that results significant increase in ionic radius that exactly adverse to positive ions.

Across the period, ionic radii decreases.

Positively charged ion has less ionic radius than negatively charged ion.
