unit 5

polarity

how unevenly electrons are shared in a bond molecule

polarizibilty

How easily an electron cloud can be distorted

dipole moment

A measure of how polar a bond or molecules

vesper

models used to show how atoms bonds and range in a molecule

electro negatively

How strongly an atom attracts electrons in a bond

polar covalent

Bond were electrons are shared unequally

non covenant

A bond electrons are shared equally

ionic

A bond formed by transfer of electrons between atoms

intramoleculer force

Forces holding atoms together within molecule

intermolecular

Forces between different molecules

LDF

We attractions caused by temporary electron movement

DD

Attraction between polar molecules

ion dipole

Attraction between an ion and a polar molecule

surface tension

How strongly molecules stick together at liquid surface

HBF

Strong Dipole attraction involving hydrogen with nitrogen oxygen and fluorine

capillary

Liquid rising in a narrow tube due to the attraction forces

viscosity

How resistant and liquid is to flowing

phase changes

transitions between salt liquid and gas

heat of fusion

Energy needed to boil a solid

heat of vaporization

the energy needed to boil a liquid into a gas

vapor pressure

pressure of gas above its liquid

normal BP

temperature where vapor pressure equals atmospheric pressure

MP

temperature were solid becomes liquid

phase diagram (triple and critical)

graph showing states of matter and special points where phase changes
