Question Analysis
This question involves comparing the radius of an anion to its parent atom.
The main focus is on the size change when an atom gains electrons to form an anion.

Key Concept Explanation
An anion forms when an atom gains valence electrons. Adding electrons increases electron-electron repulsion in the electron cloud, causing it to expand and resulting in a larger radius.

Step-by-Step Solution
1. Recall the size relationship between an anion and its parent atom.<...
