Read Section 1.1 of Unit D in Text Answer Q 1-3 Nucleus Page 43 Page 44

3. Connection to the Periodic Table of Elements (p. 20 D) 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 6 C Carbon 12.001 Atomic Number = # of Protons / Electrons Symbol = 1st letter always capital Atomic Mass = Protons + Neutrons

4. Reading Atoms on the Periodic Table 16 S Sulfur 32.066 13 Al Aluminum 26.982 11 Na Sodium 22.990 Protons: Neutrons: Electrons: Protons: Neutrons: Electrons: Protons: Neutrons: Electrons: Page 46

5. Atomic Structure Notes Continued Bohr Model - model that shows where particles are located in atoms. Valence electrons – outermost energy level Carbon: 6 Protons How many valence electrons? 6 Neutrons 6 Electrons Page 46

6. Bohr Model Practice: Use the information to make a Bohr model Carbon: 6 Protons 6 Neutrons 6 Electrons Nitrogen: 7 Protons 7 Neutrons 7 Electrons Oxygen: 8 Protons 8 Neutrons 8 Electrons Page 46

7. Practice: Determine Protons, Neutrons and Electrons, Draw a Bohr Diagram 12 Mg Magnesium 24.305 5 B Boron 10.811 10 Ne Neon 20.180 Page 46

Thursday, November 1, 2012 Friday, November 2, 2012 Thursday, November 1, 2012 Friday, November 2, 2012 • Practice Bohr Models • Finish Pure Substances vs. Mixtures Graphic Organizer • Bohr Models • Pure Substances vs. Mixtures • Warm up: • Atoms of the same element are alike / different. • Protons are positive / neutral / negative. • Protons are inside / outside the nucleus. • Neutrons are positive / neutral / negative. • Neutrons are inside / outside the nucleus. • Electrons are inside / outside the nucleus. • The overall charge of the nucleus is positive / neutral / negative. Pure Substances – same composition throughout (atoms, elements, compounds) Mixtures – physical combinations • Homework: • Practice Bohr Models • Finish Pure Substances vs. Mixtures Graphic Organizer Page 45 Page 46

9. Monday, November 5, 2012 Tuesday, November 6 2012 Monday, November 5, 2012 Tuesday, November 6, 2012 • Finish Periodic Table worksheet • Introduction, Organization and History of the Periodic Table Warm up: Determine what element this Bohr model is representing. How did you come to this conclusion? Draw a Bohr model for Helium and Neon – can you make any observations that make these two alike in any way? Make a t-chart and compare and contrast mixtures and pure substances. • Homework: • Finish Periodic Table Worksheet • - Parts 1 and 2 ONLY Page 47 Page 48

10. 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
