Bond
... In a polar covalent bond, the electrons are more attracted to the atom with the greater electronegativity. This results in a partial negative charge on that atom. The atom with the smaller electronegativity value acquires a partial positive charge. Molecular Polarity Molecules composed of covalently ...
