There are two types of covalent bonding:

1. Polar bonding results with an unequal sharing of electrons. A polar bond is a type of covalent bond between two atoms or more in which electrons are shared unequally. Because of this, one end of the molecule has a slight, relative negative charge and the other a slight, relative positive charge. For example: H2O; here hydrogen has a slight positive charge and oxygen has a slight negative charge.
2. Non polar bonding results when two identical non-metals equally share electrons between them. Non polar bonds are formed by bonding between non-metals consists of two electrons shared between two atoms. For example: O2
