Matter: a physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy.
Pure Substances: are made of only one type of atom or only one type of molecule.
Example: an ice cube would be a Pure Substance because it is only made out of one type of atom.
Element: If all atoms in a substance have the same identity, that substance is an Element.
Example: oxygen, hydrogen, sodium, chlorine, lead, and iron are all elements.
Compound: a substance formed when two or more chemical elements are chemically bonded together.
Example: Compounds can be water ( or hydrogen oxide ) H2O; and Sodium Chloride, NaCl.
Mixture: a material made up of two or more substances that can be easily separated by physical means.
Example: a mixture of oil and water.
Homogeneous: A mixture which has uniform composition and properties throughout.
Example: air is a homogeneous mixture of gases.A teaspoonful of table salt stirred into a glass of water also makes a homogeneous mixture.
Solutions: A homogeneous mixture of particles so small that they cannot be see with a microscope and will never settle to the bottom of their container. Solution remains constantly and evenly mixed.
Example :salt water, rubbing alcohol, and sugar dissolved in water.
Heterogeneous: A mixture is a combination of two or more pure substances in which the original substances retain their chemical properties.
Example: Salt and pepper, chocolate chip cookies, or a Twix™ candy bar
Suspension: Heterogeneous mixture containing a liquid in which visible particles settle.
Example: muddy wate,salt water, sand in wate
Colloid: A type of mixture with particles that are larger than those in solutions but not heavy enough to settle out.
Example: whipped cream, mayonnaise, milk, butter, gelatin, jelly, muddy water, plaster, colored glass, and paper.
