hydrogen bonds

Front

type of molecular attraction in which a hydrogen atom covalently bonded to an electronegative atom (e.g., O, N, F) in one molecule is attracted to an electronegative atom in a different molecule or in another part of the same molecule

Back

dipole

Front

a molecule that has two poles, or regions, with opposite charges

Back

heat of fusion

Front

The amount of energy required for the solid at its melting point to become a liquid

Back

polarizability

Front

the ease with which the electron distribution in the atom or molecule can be distorted

Back

heat of vaporization

Front

The amount of energy required for the liquid at its boiling point to become a gas

Back

surface tension

Front

a force that tends to pull adjacent parts of a liquid's surface together, thereby decreasing surface area to the smallest possible size

Back

interstitial alloy

Front

a mixture formed when small atoms fill holes in a metallic crystal

Back

London Dispersion forces

Front

The intermolecular attractions resulting from the constant motion of electrons and the creation of instantaneous dipoles

Back

dipole moment

Front

the charge on a molecule is not evenly shared (ex. water)

Back

cohesion

Front

Attraction between molecules of the same substance

Back

adhesion

Front

An attraction between molecules of different substances

Back

dipole-dipole forces

Front

the attractions between oppositely charged regions of polar molecules

Back

substitutional alloy

Front

some of the host metal atoms are replaced by other metal atoms of similar sizes

Back

vapor pressure

Front

pressure exerted by a vapor over a liquid at equilibrium
