A single covalent bond is formed by sharing of one pair of electrons between the atoms, each atom contributing one electron.
Ex: Molecule of hydrogen [H-H]
A double covalent bond is formed by sharing of two pairs of electrons between two atoms.
Ex: Molecule of oxygen [O=O]
A triple covalent bond is formed by sharing of three pairs of electrons between two atoms.
Ex: Molecule of nitrogen [N≡N]
