    The coordination number of cations and anions in calcium fluoride structure are respectively

    A) 4, 4

    B) 6, 6

    C) 4, 8

    D) 8, 4

    Correct Answer: D

    Solution :

    [d] In \[CA{{F}_{2}}\] structure, \[C{{a}^{2+}}\]  ions occupy all the corner and the face centre positions in fcc unit cell while \[{{F}^{-}}\] ions occupy all the tetrahedral voids. \[\therefore \] The coordination number of cations and anions in \[Ca{{F}_{2}}\] type structure will be 8, 4.
