(a) Cl− ions form fcc lattice and Na+ ions occupy all octahedral voids of the unit cell
(b) Ca2+ ions form fcc lattice and F− ions occupy all the eight tetrahedral voids of the unit cell
(c) O2− ions form fcc lattice and Na+ ions occupy all the eight tetrahedral voids of
(d) S2− ions form fcc lattice and Zn2+ ions go into alternate tetrahedral voids of the unit cell
