CLASSIFYING MATTER pure substance element • Has mass • Made up of two and volume or more different particles/ particles • Made up of only substances mixture mixed together. one type of particle matter compound heterogeneous mixture • Made up of all the same particles called particles molecules which are called atoms two or more different atoms that are combined in fixed proportions homogeneous mixture • Made up of different particles which blend well and are uniformly distributed.

heterogeneous mixture • Made up of different particles which are NOT ___________. uniformly distributed • The different particles are so large that they do NOT evenly mix with one another (e. g. salt and pepper mixture) or they are chemically unable to mix with one another (e. g. oil and water). However, some appear as if they are evenly mixed even when they are not (e. g. paint).
