  1. Today in Science • You Will Need: • Pencil, Text Book Periodic Table • 2. Colored Pencils • 3. Alien Juice Bar – 2 pages 3 sides – Bookshelf – Please Staple • 3. Electrons and Chemical Bonding- 2 pages-4 sides + ½ sheet Staple and Due Sometime Today • 4. Progress Notice - Due by tomorrow to earn regular credit

  2. Do You Remember? Type of bonds between metals and nonmetals would most likely be? What does an inhibitor do for a chemical reaction? What side of the chemical equations are the reactants? Why do metals tend to give away their electrons? Since metals give away their electrons, what type of IONS do they form? Why?

  3. Do You Remember? Why do Potassium and Iodine bond? What type of bonds form crystal lattices? What type of Bond…. CaBr2? Why? What type of Bons….Fe2O3? Why? Where are the Transition Metals on the Periodic Table? When do particles become more ordered: sublimation, condensation, melting or evaporation? Same or different density? Why? Gold Gold

  4. Forming Sodium Chloride • Explain: • Side One: • Why does sodium become an ION? • Why does chlorine become and ION? • 3) Why do these two elements do this? • Side Two: • Why is sodium a POSITIVE ION? • Why is chlorine a NEGATIVE ION? • Why do they bond?

  5. Forming Water Molecule Page 237

  6. Forming Water • Explain: • Middle Box • Why does “sharing” their electrons help both Hydrogen and Oxygen become “happy”.
