Classification of Matter

Matter

Has mass Takes up space Everything is made up of it

Substance

Same chemical composition; pure. They stay the same all the way through; they are made up of elements and compounds

Elements- pure substances that are made up of one type of atom; atoms are the smallest part in an elements

Compounds- are 2 or more elements that are chemically bound; molecules are the smallest piece of a compound

Mixture

When two or more things are physically put together

They can be . . homogeneous (solution)- they are the same through

out, when something dissolves into something

ex: Kool Aid, lemonade

Heterogeneous- they have compositions that vary

ex: cereal and milk

Heterogeneous

Are made up of suspensions and colloids Suspension- are particles that are big enough

to be seen and they settle out

Colloid- are in a gel, foam, or cream form. The particles do not settle but they are larger than the solution
