The correct response is:
Cl; it takes much more energy to pull an electron away from a valence shell that is nearly full.
Explanation: Chlorine has a high ionization energy because it has a nearly full valence shell (7 out of 8 electrons) and therefore requires a significant amount of energy to remove an electron. In contrast, magnesium has a lower ionization energy since it has a relatively empty valence shell (2 valence electrons) which can be removed more easily.
