Atom
the smallest particle of an element
colloid
a mixture that contains some particles that are intermediate in size between the small particles in a solution and the larger particles in a suspension (ex: fog)
Compound
a substance that is made from two or more simpler substances and can be broken down into those simpler substances
element
a substance that cannot be broken down into simpler substances (ex. one of the substances listed on the periodic table)
heterogeneous mixture
a type of mixture in which the parts of the mixture are noticeably different from one another (ex. a handful of sand which varies in grain size and color)
homogeneous mixture
a type of mixture in which the substances are so evenly distributed that it is difficult to distinguish one substance in teh mixture from another (ex. stainless steel or salt water)
pure substance
matter that always has exactly the same composition (ex. an element or compound)
matter

reactivity
