1. when two atoms with different electronegativities are bonded together, a bond dipole exists. these are displayed with an arrow originating at the atom with the electronegativity and pointing toward the atom with the electronegativity. 2. partial charges will exist on each atom when a bond exists between two atoms with different electronegativities. since the atom with a higher electronegativity will have a stronger ability to attract electrons, it will have a partial charge. the atom with a lower electronegativity will have an equal and opposite charge. as the difference in electronegativity increases, the resulting magnitudes of the partial charges will . 3. bond character is used to describe the severity of the electronegativity differences between the two atoms involved in a bond. bonds that have character correspond to a larger difference in electronegativities, and bond character corresponds to a smaller difference. 4. for example, if the electronegativity of both atom "a" and "b" in the phet are set to be equivalent, then increasing the electronegativity of atom "a" in the phet simulation and decreasing the electronegativity of atom "b" will result in a bond that is more ionic in character.
