A) \[[Ar]\]
B) \[[Ar]\,4{{s}^{1}}\]
C) \[[Ne]\,3{{s}^{2}}3{{p}^{4}}\]
D) \[[Ne]\,3{{s}^{2}}3{{p}^{2}}\]
Correct Answer: A
Solution :
Electronic configuration of \[{}_{16}S=1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{4}}\] Hence, electronic configuration of \[{{S}^{2-}}=1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{6}}=[Ar]\]
