  1. The Periodic Table BY: BRIANNA SHIELDS

  2. DO NOW • 1. What element has 7 protons? • 2. How many neutrons does Hydrogen have? • 3. How many electrons does Neon have?

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

  4. Review: Fill in the table

  5. Review: Atoms • How many protons, neutrons and electrons?

  6. How many p, n, e?

  7. How many p, n, e?

  8. How many p, n, e?

  9. How many p, n, e?

  10. Steps to creating a Bohr Model • Create a key: #p, #n, # e • Draw the nucleus w/ several rings • Put P and N in nucleus • Put E into orbits from inside to outside • 1st level holds 2 electrons • 2nd holds 8 • 3rd holds 18 • 4th holds 32 maximum numbers of e’s that each level can hold

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

  12. Bohr Model Example 6 6 6

  13. Bohr Model Example 2 2 2

  14. Bohr Model Example

  15. Bohr Model Example • Make a Bohr model of Magnesium. Don’t forget to make a key. Magnesium

  16. KEY #p= 12 #n= 12 #e= 12 Magnesium 12P 12N

  17. Draw the following Bohr Models: • Random students will be chosen to draw theirs on the board (don’t forget to make a key) • Neon • Hydrogen • Potassium

  18. Periodic Table Websites • ACS Periodic Table • http://www.webelements.com/

  19. 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?

  20. The Periodic Table- Video

  21. 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...

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

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

  24. 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

  25. Group 1= Alkali Metals

  26. Group 2= Alkaline Earth Metals

  27. Gp 17= Halogens

  28. Gp 18= Noble Gases

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

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

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

  32. Periodic Table Trends 5. Metals= everything to left of stair step line A. Usually have high melting points. B. Shiny when cut. C. Mostly tough, strong, malleable and ductile. D. Good conductors of heat. E. Good conductors of electricity. F. Form alloys Periodic Table Trends

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

  34. Periodic Table Trends 6. Non-Metals A. dull B. poor conductors C. brittle D. lower densities E. lower melting points F. some are solids, some liquids, and some gases Periodic Table Trends

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

  36. 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)

  37. 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

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

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

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

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

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