Powor of the Periodic Table Day 4

  1. 1. You will Need: 1)Pencil, Colored Pencils – 2)Power of the Periodic TableMovie Notes – Picked last week (3 pages 4 sides) 3) Organizing the Elements + Questions- 1 page 2 sides
  2. 2. Reminder 1)Retakes – opportunities- 1) Tuesday before school and at lunch 2) Thursday before school and at lunch
  3. 3. 1)Complete chart at the bottom of Movie Notes. (Pg 4) 2)Using your Textbook, complete information for Metals, Nonmetals and Metalloids from the pages indicated 3)Use your Movie Notes to complete the questions. 1)No complete sentences…just give the answer 4)This assignment is due Tomorrow at the beginning of class.
  4. 4. Color & Label ALKALI METALS BLUE …except for Hydrogen
  5. 5. Atomic Number 1. 1. 2. Chemical Symbol 2. 1. Abbreviation of element (some from LATIN name) Element Name 3. 1. Full name provided below symbol Atomic Mass Number 4. 1. Atomic Mass on the Periodic Table represents a “weighted average” of the mass of all the naturally occurring ISOTOPES of each element. (based on mass & abundance of each isotope.) Number of PROTONS (Unique to each element) Number of ELECTRONS (IF Atom is NEUTRAL) 2. 3. Sum of the particles in the nucleus Represents total count of protons and neutrons Positively charged because neutrons have no charge and protons are positive
  6. 6. Isotopes of Hydrogen
  7. 7. Most Common Isotope Have you noticed that some elements on the periodic table have decimal points?  This is because the Atomic Mass Number is the weighted AVERAGE of all the known isotopes.  In order to know the MOST COMMON ISOTOPE… round the Atomic Mass Number to the nearest whole number.  Write the MOST COMMON ISOTOPE by giving the element symbol +rounded number.  Examples: C 12 or Rb 86 
  8. 8. Valence – Periodic Clue for Bonding Family # 1 2 13 14 15 16 17 18 Valence # 1 2 3 4 5 6 7 8 1. This Pattern works for the “TALL” columns. 2. Since there can not be any more than 8 valence electrons….it’s a quick clue. 3. This pattern does not work for the “SHORT” columns.
  9. 9. Color & Label TRANSITION METALS GREEN
  10. 10. Color & Label METALLOIDS PURPLE Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium
  11. 11. Color & Label HALOGENS ORANGE + Hydrogen
  12. 12. Color & Label NOBLE GASES YELLOW
  13. 13. Color & Label RARE EARTH METALS RED
  14. 14. •Whatever you have not completed. (4 pages 6 sides) •Due Tomorrow at the beginning of class.
