Question

Are Ionic bonds weak?

Answer 1

1. Chemical bonds are the forces of attraction between atoms or molecules that hold them together in the form of a chemical compound.
2. Different types of bonds can be formed between atoms on the basis of the strength of the forces between them. This strength in turn depends upon the distance between them. On the basis of types of interaction/attraction between atoms, bonds are classified as - Ionic bonds, Covalent bonds, Dative bonds, Dipole-dipole interactions and Ion-dipole interactions.
3. Out of all these Ionic bonds are strongest in nature. An ionic bond is formed between two atoms when one atom gives its valence electron and the second one accepts the valence electron in order to gain stability (complete transfer of electron). In such a type of bond, atoms are held together by strong electrostatic forces as the atom which gains the electron acquires a negative charge and the one which gives the electron acquires a positive charge.
4. Since ionic compounds are held by strong electrostatic forces they have high melting and boiling points and are polar in nature. For example- Sodium chloride $\left(\mathrm{NaCl}\right)$ is an ionic compound.

So, No Ionic bonds are not weak. They are the strongest bonds.
