Answer:
The electrostatic attraction between the opposite charge, is called ionic bond.
Ionic bonds are very strong, that's why melting point and boiling point is very high.
Explanation:
Ionic bonds are also called the electrovalent bond. When a positively charged ion makes the bond with negatively charged ion, then ionic bond is formed. The ions are formed a solid lattice, which is regular in pattern. Ionic bonds are very strong, that's why melting point and boiling point is very high. Basically ionic bond forms the ionic compound.
Ionic compounds have some properties like: they are hard, form crystal lattice not molecules, conduct electricity in liquid medium, and high melting and boiling point, which makes the structure different.
