Question

electrovalent compounds are usually should and hard in nature this is due to​

Answer 1

Explanation:

They have high melting and boiling points. This is because a considerable amount of energy is required to break the strong inter-ionic attraction between the molecules. These are solids and are somewhat hard because of the strong force of attraction between the positive and negative ions.

Answer 2

Answer:

strong inter-ionic force of attraction

Explanation:

Electrovalent or ionic bonds are formed due to the exchange of ions resulting in oppositely charged ions, cations and anions, in a chemical compound. The strong electrostatic force of attraction between the ions makes the bond very strong. Thus they are usually hard and solid in nature.
