Ionic compounds are formed by ions but there also exists a repulsive force between ions for like charges. Since the electrostatic force of attraction between opposite charges is much higher, it makes the ionic compounds stable.
What do you mean by Electrovalency ?
The number of electrons that an atom of an element loses or gains to form an electrovalent bond is called its Electrovalency.
