Distinguish between ionic bond and covalent bond.

Ionic bond :

1. It is formed by the transfer of electrons from one atom to another.

2. It is formed by the transfer of electrons from one atom to another.

3. In this, oppositely charged ions are formed.

4. There are no multiple ionic bonds.

5. This bond usually exists between metal and non-metal atoms.

6. e.g. NaCl, CaCl₂

Covalent bond :

1. It is formed by sharing of electrons. 

2. Atoms are held together due to shared pair of electrons.

3. In this, oppositely charged ions are not formed.

4. Covalent bonds may be single or double or triple bonds.

5. This bond usually exists between nonmetal atoms.

6. e.g. H₂,Cl₂
