Polarity

Ionic

metal + nonmetal, full charges

Polar

non metal + different nonmetal, partial charges

Non polar

nonmetal + same nonmetal, no charges

Covalent

nonmetal + nonmetal

Metallic

metal + metal

Boiling point

the temp at which the vapor pressure of a liquid equals the external pressure surrounding the liquid

Vapor pressure

the equilibrium pressure of a vapor above its liquid (or solid)

Viscosity

A liquid’s resistance to flow

Solubility

The ability of a solid, liquid, or gas to dissolve in a solid, liquid, or gas solvent

Surface tension

The tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid which tends to minimize surface area

Intermolecular forces

attractions between molecules

Intramolecular forces

attractions within a molecule

Dipole-dipole

Attractions between polar molecules

Hydrogen Bonds

Attractions between polar molecules that have a particularly high difference in EN (strong dipole-dipole attractions)

Dispersion

Attractions between neutral atoms or nonpolar molecules
