Q. The $ZnS$ structure is cubic. The unit cell may be described as a face centered sulphide ion sub-lattice with zinc ions in the centers of alternating mini cubes made by partitioning the main cube into eight equal parts. The sum of the nearest neighbors around each $Zn ^{2+}$ and $S ^{2-}$ ion in the unit cell with be equal to

The Solid State

Solution:

Coordination number of $Zn ^{2+}: S ^{2-}=4: 4$
so $4+4=8$
