A) \[{{K}^{+}}\]
B) \[C{{a}^{+2}}\]
C) \[C{{l}^{-}}\]
D) \[{{S}^{-2}}\]
Correct Answer: D
Solution :
For isoelectronic species, greater the nuclear charge stronger the attraction for the same number of electrons and smaller the ion. Order of ionic size, \[C{{a}^{+2}}<{{K}^{+}}<C{{l}^{-}}<{{S}^{-2}}\].You need to login to perform this action.
