<human>: How can I determine if a molecule is polar or nonpolar?
<bot>: To determine if a molecule is polar or nonpolar, you need to look at the number of atoms that are involved in the bond. Polar molecules have more than one atom and nonpolar molecules have only one atom. Additionally, polar molecules have an unequal distribution of charge between the two ends of the molecule, while nonpolar molecules have equal charge on each end.
