Explain

Ionic solids are hard and brittle.

Class 12th NCERT - Chemistry Part-I 1. The Solid State

Answer :

Ionic solids are hard and brittle because in ionic solids the constituent particles are ions and they are held together in 3- dimensional arrangements by the electrostatic force of attraction. So, due to strong electrostatic force, these charged ions are held together in fixed position.
