Vedclass · Answer

(B) In the $CaF_2$ (fluorite) structure,the $Ca^{2+}$ ions form a face-centered cubic $(fcc)$ lattice.Each $Ca^{2+}$ ion is surrounded by $8$ $F^{-}$ ions,and each $F^{-}$ ion is surrounded by $4$ $Ca^{2+}$ ions.Therefore,the coordination number of the cation $(Ca^{2+})$ is $8$ and the anion $(F^{-})$ is $4$.Thus,the correct arrangement is $8:4$.

In the calcium fluoride structure,the coordination number of the cation and anion are respectively:
