In the PhET simulation window, click the Two Atoms menu in the top left corner of the screen. Click on the partial charges check box to see the partial charges of the atoms. Vary the electronegativity of atom A and atom B and observe the effects on the partial charge of each accordingly.
Use the PhET to complete the sentences describing how electronegativity is related to bond dipole experienced by the molecule.
