Is ICl2- Polar or Non-polar?

Is ICl2- polar or non-polar? I know that it is symmetrical with Cls on both side of the I atom, but do the 3 lone pairs create a dipole moment because it's an odd number? Thanks!

If a molecule has a molecular geometry of linear and both of the atoms on the sides of the central atom are the same, then it will not be polar. This is because all of the dipole moments will cancel out with the vectors and therefore too this one is nonpolar. Hope this helps!

ICl2- would be nonpolar because dipoles are created only from bonded electrons. The 3 lone pairs do not have a strong enough force to create a dipole in this molecule.
