The correct answer is: Chlorine (Cl) has a higher ionization energy than magnesium (Mg).
This is because ionization energy refers to the amount of energy required to remove an electron from an atom. Chlorine has a greater effective nuclear charge (the positive charge of the nucleus) compared to magnesium because it has a higher atomic number and more protons. Therefore, the electrons in chlorine's valence shell are held more tightly than those in magnesium, requiring more energy to remove them.
