Which has a higher ionization energy: chlorine (Cl) or magnesium (Mg)? Why? Select the best answer.(1 point)
Responses
Cl; it takes much more energy to pull an electron away from a valence shell that is nearly full.
Cl; it takes much more energy to pull an electron away from a valence shell that is nearly full.
Mg; it takes more energy to pull two electrons away from magnesium(Mg) than it does to take them from chlorine(Cl).
Mg; it takes more energy to pull two electrons away from magnesium(Mg) than it does to take them from chlorine(Cl).
Mg; magnesium has more valence electrons than chlorine.
Mg; magnesium has more valence electrons than chlorine.
Cl; it takes less energy to add an electron to a valence shell that is nearly full.
