Matter is a physical substance in general, as distinct from mind and spirit; that which occupies space and possesses rest mass, especially as distinct from energy.
Matter has two sections and they are Pure Substance and Mixture.
Pure Substance are defined as substances that are made of only one type of atom or only one type of molecule.
A mixture is a substance made by mixing other substances together. Example: trail mix, a portion salad
An element is a substance that cannot be decomposed into simpler substances by chemical means, and is made up of atoms all with identical number of protons.
A compound is a material made up of two or more parts or elements. Example: carbon dioxide (carbon and oxygen).
Homogeneous is composed of parts or elements that are all of the same kind. Example: Salty water — a mixture of salt and water.
Heterogeneous is composed of parts of different kinds; having widely dissimilar elements or constituents. Example: sandy water
A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase some time after their introduction. Example: muddy water
A homogeneous, noncrystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance. Colloids include gels, sols, and emulsions; the particles do not settle and cannot be separated out by ordinary filtering or centrifuging like those in a suspension.
