What is the relationship between ionization energy and atomic radii?
A) Energy increases as radii increase.
B) Energy is negative for all large radii.
C) Energy decreases as radii decrease.
D) Energy decreases as radii increase
E) Energy increases as as radii decrease

Question

Quizplus · Accepted Answer

The ionization energy is the amount of energy required to remove an electron from an atom. As the atomic radius increases, the distance between the nucleus and the outermost electron shell increases, resulting in a weaker attractive force between the nucleus and the electrons. As a result, it requires less energy to remove an electron, meaning the ionization energy decreases. Therefore, the correct answer is D, energy decreases as radii increase.
