Let's use Ne as our base, since noble gasses can't become ions. It has 10 protons and 10 electrons.

you make a halogen ion and an alkali metal ion so that they both have 10 electrons.

For ionic radius, anions (negatively charged) have large radii and cations (positively charged) have small radii.
