In ionic solids, which ions usually form the close-packed structure, and which ones occupy the voids?

Options

  1. AThe smaller ions form the close-packed structure, and the larger ions occupy the voids.
  2. BThe larger ions form the close-packed structure, and the smaller ions occupy the voids.
  3. CThe anions form the close-packed structure, and the cations occupy the voids.
  4. DThe cations form the close-packed structure, and the anions occupy the voids.

Correct answer

C. The anions form the close-packed structure, and the cations occupy the voids.

Step-by-step solution

In ionic solids, the anions (usually larger ions) form the close-packed structure, and the cations (usually smaller ions) occupy the voids.
