Unformatted text preview: electronegativity, the electrons of the atoms are equally shared and the bond is said to be nonpolar (with no charge attraction). When covalent compounds are formed between atoms which have very different electronegativities, the electrons of the two atoms are not shared equally. The electrons that are spinning around both atoms will be attracted to the atom which has the stronger electronegativity, so that the electrons spend more time closer to the nucleus of that atom than in the field of the atom with a weaker electronegativity. A compound (or molecule) formed by the unequal sharing will have one end functionally slightly negative (the end with the atom having a strong attraction for electrons) and the other end of the molecule slightly positive, resulting in a polar covalent bond and molecule....
