  1. Tuesday 10/21/08 1st 5: (New Sheet) Choose 2 elements. Compare & contrast them using a Venn Diagram. TURN IN: Atomic Rule Book TODAY: • Finish Atomic Rule Book (Definitions) • Paint chips & periodic table trends HOMEWORK: Periodic Table Trends notes

  2. Atomic S’mores Rule BookHow do you play the game? Click here for booklet folding instructions • Cover: Labeled Model of Atom + Title + Name • Page 1: S’more model of an atom with key • Page 2: The “rules” of the game (see next slide) • Page 3: Draw 3 Examples (H, Oxygen, and ?) • Page 4: Ionic Bonds (leave blank for now) • Page 5: Covalent Bonds (leave blank) • Page 6: Vocabulary (see notes) • Back cover: vocabulary (cont.) Vocabulary Atom Matter Proton Neutron Electron Quark Meson Ion Isotope Ionic Bond Covalent Bond Subatomic Particle

  3. Atomic S’more Rules • # P = # e in an electrically neutral atom • Atomic Number = # Protons • Atomic Mass = #P +#N • Atomic Mass – Atomic # = # Neutrons • Protons & Neutrons are in nucleus • Electrons are around the nucleus in energy shells

  4. Atomic Definitions • Matter: • Atom • Proton • Neutron • Electron • Subatomic Particle • Meson • Quark • Isotope • Ion • Ionic Bond • Covalent Bond

  5. Paint Chip Periodicity • Create a chart with rows & columns • Must use every paint chip • Must be able to explain why/how you organized it

  6. Dmitri Mendeleev’s Periodic Table • Russian Chemist • In 1869, he noted that the repeating patterns of behavior could be arranged in a sequence of elements giving rise to the "Periodic Table" of the elements.

  7. GILBERT NEWTON LEWIS • American Chemist (1875-1946) • Lewis Dot Structures: Diagrams of elements and their valence electrons. • Help show how/why/if elements bond
