Question

The outer most electronic configuration of the most electronegative element is:

• A. $n{s}^{2}n{p}^3$
• B. $n{s}^{2}n{p}^4$
• C. $n{s}^{2}n{p}^5$
• D. $n{s}^{2}n{p}^6$

Answer 1

The correct option is C $n{s}^{2}n{p}^5$

Halogens are most electronegative.

Therefore outer electronic configuration is $n{s}^{2}n{p}^5.$

Option C is correct.
