2. Agenda or Summary Layout A second line of text could go here Chemistry: The Study of matter and the changes is undergoes The Periodic Table is organized according to the elements’ atomic number, mass number, and atomic mass These numbers assist in conversion from one unit to another Chemistry Physical Properties, Physical Change, Chemical Properties, Chemical Changes Matter Changes Avogadro’s Number & The Mole Atomic Structure Periodic Table The atom consists of 2 main parts: the nucleus and the electron cloud

3. Matter Anything that has mass and occupies space Matter is subdivided into three general classes, based on chemical or physical properties Compound Element Mixture The study of matter and the changes it undergoes Chemistry Homogenous Mixture “the same throughout” Ex: NaCl, K, H 2 0 Heterogeneous Mixture “not the same throughout” Ex: Chex Mix

4. Changes in which no new kinds or matter are formed. Ex: Phase changes Mixtures can be separated by physical separation Filtration Evaporation Thawing Distillation Boiling Changes that produce new kinds of matter that show brand new properties. Examples Combustion (burning) Composition and Decomposition Color Changes Energy Changes Light Emitted Gas Given Off pH Changes Changes that Matter Undergoes I <3 Chemistry Compounds are the products of chemical changes. They cannot be broken down physically, but can be separated chemically

5. Characteristics that undergoes no change in composition Examples Mass Length Volume Density Solubility Melting and Boiling Point Conductivity Color Hardness Mixtures are separated due to their physical properties Describes how a substance changes into something new. By asking questions such as does it burn or react with acids helps determine the chemical properties of a substance Properties of Matter I <3 Chemistry
