Electrovalent compounds have oppositely charged ions that are held tightly by strong electrostatic forces which make it a closely packed structure. The thermal energy of the ions is less and so they remain are closely bound to form a crystal lattice. Therefore, the electrovalent compounds are hard.
However, when a strong external force is applied, the layers of ionic solids gets displaced. This displacement leads to electrostatic repulsions in between the layers. Therefore, the electrovalent compounds are said to be brittle.

Very Good question. Thanks for asking it.
Electrovalent compounds are also called as Ionic compounds because Ionic bond is present between the metals and Non metal .
Ionic compounds are usually crystalline solids.
For Example :
Sodium Chloride [NaCl] is a crystalline solid because their oppositely ions attract one another strongly by electrostatic force of attraction and form a regular crystal structure.
In case of Sodium Chloride, Na ⁺ ion and Cl⁻ ions are attracted by strong electro static force of attraction.
