Document Summary

Matter: anything that occupies space and has mass. Atoms: what composes matter, the fundamental building blocks of matter. States of matter: solid, liquid, and gas. Crystalline: where atoms or molecules of solid matter arrange in geometric patterns with long-range, repeating order (ex: salt and diamond) Amorphous: where atoms or molecules of solid matter do not have long-range order (ex: glass, rubber, and plastic) Free to move relative to one another. Pure substance: composed of only one type of atom or molecule (ex: helium and water) Element: substance that cannot be broken down into simpler substances (ex: copper and carbon) Compound: substance composed of two or more elements in fixed definite proportions (ex: water, table salt, and sugar) Mixture: composed of two or more different types of atoms or molecules combined in variable proportions. Heterogeneous mixture: composition varies from one region to another (ex: oil and water) Homogeneous mixture: composition is the same throughout (ex: water, salt, and sweetened tea)
