Question Analysis
This question assesses the student's understanding of the definition and application of the covalent radius.

Key Concept Explanation
The covalent radius is a measure of the size of an atom in a covalent bond. It is defined as half the distance between the nuclei of two covalently bonded identical atoms. This concept is useful in understanding the size of atoms in molecules.

Step-by-step Solution
1. Define the term "covalent radius": half the distance between the nuclei of two covalently bonded identical atoms.
2. Provide an example: the covalent radius of chlorine (Cl) can be determined by measuring the distance between the nuclei of two chlorine atoms in a Cl₂ molecule and dividing it by two.
3. Therefor...
