Ionic solids are hard and brittle. Explain

Solution
- Ionic solids are brittle and rigid.
- The strong electrostatic forces of attraction between the oppositely charged ions, which hold the particles firmly together, are the cause of the hardness.
- Ionic solids are fragile because layers of ions shift when a force is applied.
- Similarly charged ions come opposite each other and repel when a force is applied, causing the layers to slide over one another. The crystal is broken as a result.
