Question
In the Zinc Blende ($ZnS$) ideal crystal structure, the $Zn^{2+}$ cations specifically occupy:
Answer: C
💡 Solution & Explanation
In zinc blende, $S^{2-}$ ions form an FCC lattice. The $Zn^{2+}$ ions occupy half of the tetrahedral voids, specifically an alternate set of tetrahedral voids. This gives the $1:1$ stoichiometry of $ZnS$.
