Question Analysis
This question tests the basic meaning of ionization energy in simple terms. The main focus is on distinguishing ionization energy from other atomic properties like electron affinity.

Key Concept Explanation
Ionization energy is the energy required to remove an electron from an atom. A low ionization energy means an atom can easily lose an electron, while a high ionization energy means it is difficult for the atom to lose an electron.

Step-by-Step Solution
1. Eliminate options that do not involve electron removal:
A: Describes electron affinity, not ionization energy.
C: Describes covalent bonding, not ionization energy.
D: Describes nuclear fission, which is unre...
