WebCovalent bond between the elements can be either polar or non-polar. This is determined with the concept of electro-negativity. If the electrons are shared equally between the atoms then its a non-polar covalent bond. If one of the atom is electronegative, it has more tendency to attract the electrons. Then the bond is called as polar covalent ...
