Chemical bond polarity is the concept that explains the property of sharing an electron between two elements. Covalent 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 bond. This calculator is used to find the bond polarity and tendency of electro-negativity in each element.
