Question

The outermost 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

Answer: (C)

$n{s}^{2}n{p}^5$ configuration represents the most electronegative element as after gaining one electron it becomes more stable (inert, gas configuration) [electronegativity is the tendency of attracting electron].
