CHEM REVIEWER

Study of matter, its properties, and how it changes.

It includes attraction and repulsions between atoms, molecules, and surfaces, as well as other intermolecular forces.

Called the CENTRAL SCIENCE.

occurs when there is an electronegativity difference between the bonded atoms.

Occurs when electrons are shared equally between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.

cause nonpolar substances to condense to liquids and to freeze into solids when the temperature is lowered sufficiently.

occur when the partial charges formed within one molecule are attracted to an opposite partial charge in a nearby molecule.

is the attractive force between the hydrogen attached to an electronegative atom of one molecule and an electronegative atom of a different molecule.

are interactions between charged atoms or molecules.
