The correct response is:
Cl; it takes much more energy to pull an electron away from a valence shell that is nearly full.
Chlorine (Cl) has a higher ionization energy compared to magnesium (Mg) because it is closer to achieving a full outer electron shell (with 7 valence electrons) and thus requires more energy to remove an electron. In contrast, magnesium (Mg) has 2 valence electrons and readily loses them to attain a stable electron configuration, resulting in lower ionization energy.
