Read Section 1.1 of Unit D in Text Answer Q 1-3 Chemistry – The study of matter and atoms and the changes they can undergo Atoms – The building block and basic unit of all matter - Consist of a small charged particles Subatomic Particles – Atoms contain charged particles Nucleus Electron Cloud (rings) Positive – Protons Negative – Electrons Neutral – Neutrons Parts of an Atom : Tuesday, October 30, 2012 Wednesday, October 31, 2012 Nucleus Electron Cloud

Atomic Number – Number of Protons - This is how elements are arranged on the periodic table Neutral Atom –Protons = the number of Electrons Atomic Mass Number – Number of Protons + Neutrons - The total mass of the nucleus Connection to the Periodic Table of Elements (p. 20 D) 6 C Carbon Atomic Number = # of Protons / Electrons Symbol = 1 st letter always capital Atomic Mass = Protons + Neutrons

Matter Has mass or weight Takes up space (volume) Cannot occupy the same space as other matter at the same time Pure Substances Has the same composition throughout Can Occur Naturally Mixtures Formed when two or more substances are physically combined Parts can be physically separated Substances in a mixture retain their original properties Element Cannot be broken down into simper substances Compound Chemical combination of two or more different elements Cannot be physically separated Properties are entirely different properties of each element alone Homogeneous Parts of the mixture are evenly distributed Heterogeneous Parts of the mixture are not evenly distributed

Finish Periodic Table Basics Activity

Families of Elements on the Periodic Table – Part 3

Properties of …. Metals Metalloids Most are solids Can be shaped & pulled into wires Shiny / lustrous Good conductors of electricity/heat Tend to lose electrons in chemical reactions Most are Solids Can be shiny or dull Can be shaped & pulled into wires Conducts better than nonmetals but not as well as metals Most are gases Solid non-metals are brittle Not shiny, but dull Poor conductors of electricity and heat Tend to gain electrons in chemical reactions Non-metals
