the bottom left corner
Which has a higher ionization energy: chlorine (Cl) or magnesium (Mg)? Why? Select the best answer. (1 point)
Cl; it takes less energy to add an electron to 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; magnesium has more valence electrons than chlorine.
Mg; it takes more energy to pull two electrons away from magnesium (Mg) than it does to take them from chlorine (Cl).
1. the upper left
2.CI; it takes much more energy
To find the atoms with the largest atomic radius on the periodic table, you need to know the general trend of atomic radius across the periodic table. Atomic radius tends to increase as you move down a column (group) and decrease as you move across a row (period). This means that atoms on the left side and bottom of the periodic table generally have larger atomic radii.
Therefore, the choice "the bottom left corner" is the correct answer as it represents the region with the largest atomic radii on the periodic table.
Regarding the higher ionization energy between chlorine (Cl) and magnesium (Mg), ionization energy refers to the energy required to remove an electron from an atom.
The best answer is "Cl; it takes much more energy to pull an electron away from a valence shell that is nearly full" because chlorine (Cl) has a nearly full valence shell with only one missing electron. It requires a significant amount of energy to remove an electron from a stable configuration.
On the other hand, magnesium (Mg) has two valence electrons in its outer shell, making it easier to remove one or two electrons as compared to removing a single electron from a nearly full valence shell of chlorine. Hence, chlorine (Cl) has a higher ionization energy than magnesium (Mg).
