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
