If the atoms differ in
their attraction for electrons, a polar-covalent bond will be formed. Water is an example of a molecule with this
type of bond...the following illustration attempts to show how the bond is
distorted creating partial positive and negative charges on the atoms.

The
attraction of electrons to the nucleus of an atom is a very important property
of atoms and is called electronegativity. The
difference in electronegativity between bonded atoms determines the bond
polarity.
