Number of Bond
- There are 3 types of covalent bond:
- Single covalent bond – sharing of one pair of electrons
- Double covalent bond – sharing of two pairs of electrons
- Triple covalent bond – sharing of three pairs of electrons
Example
| Number of electrons | Example and type of covalent bond |
| 1 pair | type of covalent bond: Single Bond  |
| 2 pair | type of covalent bond: Double Bond  |
| 3 pair | type of covalent bond: Triple Bond  |
Formation of Single Bond (Hydrogen Molecule)
Formation of Double Bond (Oxygen Molecule)
Formation of Triple Bond (Nitrogen Molecule)
