Covalent Bond•A link between atoms due to the sharing of two electrons. This bond forms between atoms of two nonmetallic elements.–If the electrons are shared equally, there is a even distribution of the negative charge for the electrons in the bond, so there is no partial charges on the atoms. The bond is called a nonpolar covalent bond. –If one atom in the bond attracts electrons more than the other atom, the electron negative charge shifts to that atom giving it a partial negative charge. The other atom loses negative charge giving it a partial positive charge. The bond is called a polar covalent bond.
