    Dipole Moment, NO3-, XeF4, SF3+, Chemisty,
    I would like to know how to figure out if the following: NO3-, XeF4, SF3+, have DIPOLE MOMENT.
    Why do they have or don't have dipole moments? :confused: :confused:

    I am so bad at this :( :(

    THXXXXX :p :p

    Dipole moment (µ) is the measure of net molecular polarity, which is the magnitude of the charge Q at either end of the molecular dipole times the distance r between the charges.

    µ= Q X r

    Dipole moments tell us about the charge separation in a molecule. The larger the difference in electronegativities of bonded atoms, the larger the dipole moment. For example, NaCl has the highest dipole moment because it has an ionic bond (i.e. highest charge separation).
