In chemistry, this type of unequal sharing is the basis of bond polarity and dipole moments. ... Polar molecules exhibit a large difference in electrical charge (a positive end and a negative end), otherwise known as adipole moment. For example, ammonia (NHsub3) is a polar molecule

A dipole moment is simply the measure of net polarity in a molecule.
For example, ammonia (NHsub3) is a polar molecule. As you can see, ammonia consists of one nitrogen atom covalently bonded to three hydrogen atoms. Since nitrogen has a stronger attraction for electrons than hydrogen, the electrons that they share are drawn towards nitrogen and away from hydrogen. This gives nitrogen a partial negative charge (which is denoted by by a minus sign on N) and hydrogen a partial positive charge (which is denoted by a plus sign on each H). The presence of both a positive and negative charge on the molecule means that ammonia is polar and, therefore, exhibits a net dipole moment.
