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 :   $$n{s^2}\,n{p^5}$$
Solution :
TIPS/Formulae : The element having highest tendency to accept the electron will be most electronegative element.
Configuration $$n{s^2},\,n{p^5}$$  means it requires only one electron to attain nearest noble gas configuration. So, it will be most electronegative element among given choices.
