A) \[n{{s}^{2}}n{{p}^{5}}\]
B) \[n{{s}^{2}}n{{p}^{6}}\]
C) \[n{{s}^{2}}n{{p}^{4}}\]
D) \[n{{s}^{2}}n{{p}^{3}}\]
Correct Answer: A
Solution :
In any period, halogens are most electronegative elements (VII A group or 17 group). Halogens have seven electrons in their outermost shell. They readily gain one electron to complete their octet. Electronic configuration of halogens is, \[n{{s}^{2}}n{{p}^{5}}\].You need to login to perform this action.
