Ions are the constituent particles of ionic solid. Such solids are formed by the three-dimensional arrangement of cations and an ions bounded by strong coulombic forces. These solids are hard and brittle in nature. They have high melting and boiling point. Some information are given in List - I and List - II, match the List-I with List-II

List -I List II

(I) Co-ordination number of $C a^{2 +} and F^{-}$ in fluorite structure (P) 8, 4

(II) Co-ordination number of $Z n^{2 +} and S^{2 -}$ in zinc blende structure (Q) 8, 8

(III) Co-ordination number of $C s^{+} and C l^{-}$ in $C s C l$ (bcc type) structure (R) 4, 8

(IV) Co-ordination number of $L i^{+} and O^{2 -}$ in antifluorite structure (S) 4, 4
