Is it true that ionic compounds are hard solids?

The above statement is true.
Ionic compounds are hard solids. These compounds are hard and brittle because they are made up of oppositely charged ions which are held together by a strong electrostatic force of attraction. Due to these strong electrostatic forces of attraction between cation and anion, ionic solids exist as hard solids at room temperature. Ionic compounds have high melting and boiling points. These are hard and brittle.
