Question

Why does a chlorine atom tend to form an ion by gaining one electron?
Options
A It has one electron more than a stable noble gas structure
B It has a full valence shell
C It has one electron short of a stable noble gas structure
Correct Answer
D It has two valence electrons
Correct Answer

Option C is the correct answer.

Detailed Explanation

Chlorine (2,8,7) has one electron short of a stable noble gas structure (2,8,8). By gaining one electron, it achieves a stable configuration similar to argon, forming a Cl⁻ anion.

Hint

Chlorine needs one electron to complete its octet.
