Lattice Structures of Ionic Compounds

Sodium Chloride

1. Determine the number of sodium ions per unit cell.

2. Determine the number of chloride ions per unit cell.

3. What is the empirical formula of sodium chloride based on the relative number of each ion in the unit cells?

4. Determine the coordination number for the sodium ions AND for the chlorine ions.

5. What is the ratio of the coordination numbers, does this make sense with the empirical formula for sodium chloride?

6. Is the empirical formula determined from the lattice structure in agreement with the one predicted by the typical ion charges?

7. Are either of the ions arranged in one of the basic cubic unit cells (simple, body-centered, face-centered)?
