1 Polarity (physics), a physical alignment of atoms. 2  Cell polarity, differences in the shape, structure, and function of cells. 3  Chemical polarity, a concept in chemistry which describes how equally bonding electrons are shared between atoms.  Polar reciprocation, a concept in geometry also known as polarity.
Molecular polarity is dependent on the difference in electronegativity between atoms in a compound and the asymmetry of the compound's structure. Polarity underlies a number of physical properties including surface tension, solubility, and melting and boiling points.
