A) \[{{F}^{+}}\] and \[Ne\]
B) \[L{{i}^{+}}\] and \[H{{e}^{-}}\]
C) \[C{{l}^{-}}\]and \[Ar\]
D) \[Na\] and \[K\]
Correct Answer: C
Solution :
Chlorine has a tendency to accept one electron to acquire inert gas configuration (octet rule). Hence, it form \[C{{l}^{-}}\] ion by taking up one electron and acquires stable configuration of\[{}_{18}Ar.\] \[C{{l}^{-}}=1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{6}}=[Ar]\]You need to login to perform this action.
