lonization energy depends on which of the following factors?
Correct answer: D. All of these options are correct
- A. Size of atoms
- B. Nuclear Charge
- C. Number of shells
- D. All of these options are correct
Explanation
Option D is correct since all of the options mention the correct reasons for the ionization energy trend and all three reasons have to be looked at to set up a trend of ionization energy. Option A is insufficient since only the size of atoms is not the factor affecting ionization energy. Though there is an increase in ionization energy as the size of the atoms decreases, this factor alone cannot be used alone to predict the trend of ionization energy. Option B is insufficient since the only nuclear charge is not the factor affecting ionization energy. Though there is an increase in ionization energy as the nuclear charge increases, this factor alone cannot be used alone to predict the trend of ionization energy. Option C is insufficient since only the number of shells is not the factor affecting ionization energy. Though there is a decrease in ionization energy as the number of shells increases, this factor alone cannot be used alone to predict the trend of ionization energy.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
