Question

What is the characteristic valence electron configuration of the halogens (Group 7A/17)?
Options
A ns¹
B ns²
C ns² np⁵
Correct Answer
D ns² np⁶
Correct Answer

Option C is the correct answer.

Detailed Explanation

Halogens (Group 7A/17) have the characteristic valence electron configuration of ns² np⁵. This means they have seven valence electrons and are one electron short of a full octet, making them highly reactive and likely to gain one electron to form anions.

Hint

Halogens are one group left of the noble gases.
