The single covalent between two atoms has one electron pair sharing form the valance shell of both the atoms. For the double and triple covalent bond the pair of electrons sharing form the valance shell of the respective atoms increases by two and three respectively. This aspects are very important in chemistry.
The cause is the different overlapping of atomic orbitals and so the type of bonds:
- single bond: sigma bond
- double bond: 1 sigma bond + 1 pi bond
- triple bond: 1 sigma bond + 2 pi bond
How many pairs of electrons two atoms share.
In single covalent bond, one pair of electron is shared between two atoms (C-C). In a double covalent bond, two pairs of electrons are shared between two atoms (C=C). Double bonds are shorter in length and more stronger than that of single bonds.
This compound makes a double covalent bond between nitrogen and oxygen.
Single covalent bonds between O and H
Bromine and fluorine are both non-metals, and the electronegativity difference between them is quite small, so the bonds will be covalent. In covalent bonds, electrons are shared between atoms in single, double, and triple bonds.
Double covalent bonds are formed by sharing four electrons between two atoms. In contrast, single covalent bonds share two electrons between two atoms.

The covalent bond in diatomic oxygen is a double bond and is stronger than the single covalent bond in diatomic chlorine.

A covalent bond that shares four electrons has a double bond between the atoms. A single bond is shown as a single dash, so a double bond is two dashes.
