Vedclass · Answer

(B) The ionic radii depend on the number of shells and the effective nuclear charge. $K^{+}$ has $4$ shells,$Na^{+}$ has $3$ shells,$Li^{+}$ has $2$ shells,and $F^{-}$ has $2$ shells. Comparing ions with the same number of shells: $F^{-}$ $(Z=9)$ has a lower effective nuclear charge than $Li^{+}$ $(Z=3)$,so $F^{-} > Li^{+}$. Comparing ions with different shells: The order is $K^{+} (4 	ext{ shells}) > Na^{+} (3 	ext{ shells}) > F^{-} (2 	ext{ shells}) > Li^{+} (2 	ext{ shells})$. Thus,the correct order is $K^{+} > Na^{+} > F^{-} > Li^{+}$.
