Polarity

Nonpolar Covalent Bond

Bond between two nonmetals that is shared equally

Polar Covalent Bond

Bond between two nonmetals that is shared unequally, creates a dipole

Dipole

Separation of partial charges

Nonpolar Molecule

Molecule that has all nonpolar bonds or has a symmetrical molecular geometry and identical bonds

Polar Molecule

Molecules that have one polar bond, non-symmetrical molecular geometry with more than one polar bond, or symmetrical geometry with nonidentical polar bonds

Solvation

Process by which polar molecules surround ions and separate them

Induced Dipole

Temporary dipole between a polar and nonpolar molecule due to random electron dispersion

Chromatography

Physical method of separating components in a mixture by exploiting differences in affinity for the molecules that make up the phases
