Explain ionic solids are hard and brittle.

Ionic solids are hard and brittle. Explain

Explain

Solution

  1. Ionic solids are brittle and rigid.
  2. The strong electrostatic forces of attraction between the oppositely charged ions, which hold the particles firmly together, are the cause of the hardness.
  3. Ionic solids are fragile because layers of ions shift when a force is applied.
  4. 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.
