Do lone pairs affect the polarity of an atom? How so?

Yes, lone pairs affect the polarity of a molecule.

If there is an individual lone pair, there won't be another pair of electrons to cancel out the dipole moment, therefore the molecule will be polar.

If there are two lone pairs, it is possible for it to not affect the polarity of the molecule if the lone pairs are arranged in such a way that their dipoles cancel out. We would need to take a look at the molecular geometry of a molecule to determine this.

Thanks!
