Question

The outermost electronic configuration of the element with least electronegativity among the following is?

• A. 2$s^2$2$p^5$
• B. 3$s^2$3$p^6$
• C. 2$s^2$2$p^4$
• D. 6$s^2$6$p^6$7$s^1$

Answer 1

The correct option is D

6$s^2$6$p^6$7$s^1$

Elements with 1 electron in the outermost shell are highly electropositive as they have the tendency to lose an $e^{-}$ and attain inert gas configuration.
