It makes up all things we use, such as water, wood, and plastic bags. We can classify matter according to its composition / arrangements of particles. © 2017 Pearson Education, Ltd.  Classification of Matter © 2017 Pearson Education, Ltd.  Classification of Matter © 2017 Pearson Education, Ltd.  Pure Substances: Elements and Compounds A pure substance is classified as a type of matter with a fixed or definite composition. an element that is composed of just one type of atom. a compound that is composed of two or more elements chemically combined in the same proportion. © 2017 Pearson Education, Ltd.  Elements Elements are pure substances that contain only one type of material. include examples such as copper, Cu; lead, Pb; and aluminum, Al. An aluminum can consists of many atoms of aluminum. © 2017 Pearson Education, Ltd.  Compounds A compound consists of two or more elements in a definite ratio. salt, NaCl table sugar, C12H22O11 water, H2O A molecule of water, H2O, consists of two atoms of hydrogen (white) for every one atom of oxygen (red). © 2017 Pearson Education, Ltd.  Compounds Contain Elements “Table salt” is a compound that contains the elements sodium and chlorine. The decomposition of salt, NaCl, produces the elements sodium and chlorine. Elements cannot be broken down further. © 2017 Pearson Education, Ltd.  Mixtures A mixture is a type of matter that consists of two or more substances that are mixed, but not chemically combined. two or more substances in different proportions that can be separated by physical methods. A mixture of spaghetti and water is separated using a strainer, a physical method of separation. © 2017 Pearson Education, Ltd.  Laboratory Separation of Mixtures (a) A mixture of a liquid and a solid is separated by filtration. (b) Different substances are separated as they travel at different rates up the surface of chromatography paper. © 2017 Pearson Education, Ltd.  Homogeneous Mixtures In a homogeneous mixture, the composition is uniform throughout the sample. the different parts of the mixture are not visible. Brass is a homogeneous mixture of copper and zinc atoms. © 2017 Pearson Education, Ltd.  Heterogeneous Mixtures In a heterogeneous mixture, the composition varies from one part of the mixture to another. the different parts of the mixture are visible. Water and copper form a heterogeneous mixture. © 2017 Pearson Education, Ltd. © 2017 Pearson Education, Ltd. © 2017 Pearson Education, Ltd.  Chapter 3 Lecture Chapter 3 Matter and Energy 3.1 – Classification of Matter Learning Objective Classify examples of matter as pure substances or mixtures.
