Pure substance

Type of matter that has a definite composition/formula to represent it.

Element

Category of matter made up of only one type of atom

Compound

Category of matter made up of two or more different types of atoms.

Mixture

Two or more types of matter that are physically combined

Heterogeneous Mixture

Mixture that does not have a uniform composition

Homogeneous

Mixture that does have a uniform composition. Also called a solution

Atom

Smallest unit of matter

Molecules

Neutral group of compounds; combination of nonmetals

Extensive Properties

Property that changes when mass of the sample changes.

Intensive Properties

Property that does not change when mass of the sample changes.

Physical Change

Change is the appearance of matter without changing its composition

Physical Property

Density, Melting Point, Boiling Point, Magnetism, Specific heat capacity, Solubility

Chemical Change

Change in appearance with a change in composition; results in formation of a new substance with new properties.

Chemical Property

Burning, Decaying, Fermenting, Digesting, Rusting

Mass

Measure of the amount of matter

Element

Fe, Ag, H, O, C

Compound

NaCl, H2O, CO2

States of matter
