  1. The Periodic Table BY: BRIANNA SHIELDS

  2. DO NOW • 1. What element has the chemical symbol K? • 2. How many neutrons does Hydrogen have? • 3. How many electrons are in the outer orbit level of aluminum? (need to make a Bohr model)

  3. GOAL • To construct Bohr models • To use the periodic table and become familiar with its elements

  4. The Periodic Table- Video What is the name for the element group in the first column of the periodic table? What is the name for the element group in the last column of the periodic table?

  5. The Periodic Table- Video

  6. Trends in the Periodic Table • ACS Periodic Table • Chemistry: WebElements Periodic Table • A Periodic Table of the Elements at Los Alamo... • Chemical Elements.com - An Interactive Period...

  7. The Periodic Table You should be coloring in and labeling your periodic table, as we take notes

  8. Periodic Table Trends 1. Atomic number increases left to right, top to bottom Periodic Table Trends

  9. Periodic Table Trends 2. Groups / Families = Vertical Columns Gp 1= Alkali metals Gp 2= Alkaline earth metals Gp 17= halogens Gp 18= noble gases Periodic Table Trends

  10. Group 1= Alkali Metals

  11. Group 2= Alkaline Earth Metals

  12. Gp 17= Halogens

  13. Gp 18= Noble Gases

  14. Periodic Table Trends 3. Periods = horizontal rows Periodic Table Trends

  15. Periodic Table Trends 4. Metalloids= along stair step line (metal and non-metal characteristics) Periodic Table Trends

  16. Periodic Table Trends 5. Metals= everything to left of stair step line Periodic Table Trends

  17. Periodic Table Trends 6. Non-metals = everything to right of stair step line (most common) Periodic Table Trends

  18. Periodic Table Trends 7. Transition elements- elements in gps 3-12 with unusual properties Periodic Table Trends

  19. Describe the locations of the elements • Ex: Neon is a non-metal located in period 2, gp 18 (noble gases) • Sodium • A metal located in period 3, gp 1, the • Nickel • A transition metal located in period 4, gp 10 • Fluorine • A non-metal in period 2, grp 17 (halogens)

  20. Describe the locations of the elements • Ex: Neon is a non-metal located in period 2, gp 18 (noble gases) • Aluminum • A metalloid in period 3, group 13 • Hydrogen • A non-metal located in period 1, gp 1

  21. How many p, e and n? Atomic Number 19 K Chemical Symbol Atomic Mass 39.10

  22. How many p, e and n? 29 Cu 63.55

  23. Review: Bohr Models • Make a Bohr Model of Lithium

  24. KEY #p= 3 #n= 4 #e= 3 Lithium 3P 4N

  25. Review: Bohr Models • Make a Bohr Model of Silicon

  26. KEY #p= 14 #n= 14 #e= 14 Silicon 14P 14N
