Question Analysis
This question tests the definition of first ionization energy using fluorine as an example. The main focus is on recognizing the correct reactant (neutral atom) and product (+1 cation) for the first ionization process.

Key Concept Explanation
First ionization energy is defined as the energy required to remove one valence electron from a neutral gaseous atom to form a +1 gaseous cation. The process is always represented as a neutral atom losing one electron.

Step-by-Step Solution
1. Recall the definition of first ionization energy: neutral atom → +1 cation + e⁻.
2. Evaluate each option:
A: Involves an anion (F⁻), not a neutral atom.
B: Matches the definition: neutral F atom → F⁺ cation + e⁻.
C: Involves a +1 cati...
