Problem
A particulate representation of MgO contains the following errors:
• Each Mg²⁺ ion is surrounded by four other Mg²⁺ ions at equal nearest-neighbor distances.
• One entire row in the third dimension is missing O²⁻ ions.
Identify both errors and briefly justify, in terms of electrostatic interactions, why each one would raise the potential energy of the solid.
