As the Atomic size increase so does Ionization Energy.

Explanation:

Atomic size is the distance from the nucleus to the valence shell. Ionization energy is the energy required to remove the most loosely held electron from a gaseous atom or ion. Ionization energy increases across a period and decreases down the family. So as the Atomic size increase so does Ionization Energy. As the Atomic size decrease so does Ionization Energy.
