Mo6-L7a: How is Matter Classified?






               Classifying Matter                                                    Matter
               Scientists place matter into one of two groups—       Anything that has mass and takes up space.
               substances and mixtures.                                  Most matter is made up of atoms.

                                                                       Substances             Mixtures

                                                                       Matter with a      Matter that can vary
                                                                    composition that is     in composition.
                                                                     always the same.

               Matter can be classified as either a substance or a mixture.

               Matter is classified according to the types of atoms and the arrangement of atoms in matter.
