Polarity is also determined by the shape of a molecule. Molecules that are symmetrical tend to be nonpolar. Molecules that are asymmetrical tend to be polar. Polarity is like a game of tug-o-war. If there is an equal "pull" on the central atom from all sides, then the molecule is nonpolar. sharepod help
