  1. Unit 4 The Incredible Periodic Table

  2. Today… • Turn in: • Get out PT Basics Poster • Our Plan: • PT Basics Questions with group • Introduce Personal PT Project • Homework (Write in Planner): • Personal PT Project • Choose topic and how to organize

  3. Daily Challenge • PT Basics Inquiry Activity • Answer the questions on the back of your PT Basics Handout with your group. • Turn in your poster and your questions when finished.

  4. Wrap Up • As a group, come up with 3 things that you learned today about the Periodic Table and be prepared to share.

  5. Today… • Turn in: • Nothing • Our Plan: • Work on your Personal Periodic Table • Wrap Up – Questions about project? • Homework (Write in Planner): • Personal PT Project – due Monday • Don’t forget a title and key!

  6. Wrap Up • What questions do you have about your Periodic Table project?

  7. Today… • Turn in: • Periodic Table Project • Our Plan: • Crash Course Video • PT Card Sort • Alphabet Brainstorm • Homework (Write in Planner): • Stop the Process due NEXT class

  8. Crash Course on the Periodic Table • http://www.youtube.com/watch?v=0RRVV4Diomg • First 5 minutes

  9. Game Time • In your team of 3 or 4, complete the Periodic Table Card Sort and complete the worksheet as a team. • Be sure to follow the requirements in the instructions for how many things you have to list.

  10. Activity Discussion • Where are the metals? • Where are the nonmetals? • Where are the metalloids? • What do things in a column have in common? • What do things in a row have in common? • What is the trend in size? • What is the trend in reactivity?

  11. Wrap Up • Alphabet Brainstorm – as a group of 4, come up with one word for each letter of the alphabet that relates to the Periodic Table. Don’t forget to look at the Word Wall!

  12. Homework • Complete p. 3 of your notes by next class. Read your textbook to answer the questions.

  13. Today… • Turn in: • Get out Stop the Process • Grade Reflections • Our Plan: • PT Puns • Notes/Label Your PT • Family Sort/Crossword Puzzle • Wrap Up – Family Clicker Review • Homework (Write in Planner): • Family Sort/Crossword Puzzle due next class

  14. Modern Periodic Table • The table is called the “Periodic Table” because elements have similar properties that occur periodically.

  15. Periods • Rows (left to right) are called periods. • All of the elements in a period have the same number of energy levels.

  16. Periods Relate to Atoms • As we increase the atomic number, the electrons fill the energy levels • Energy levels are labeled K, L, M, N, O, P, Q (or 1-7) 1. Label on your PT

  17. Label Your PT

  18. Energy Levels

  19. GROUPS • The columns (top to bottom) of the periodic table

  20. GROUPS • The elements in a group have the same number of valence electrons. • Valence electrons are the electrons found in the outermost energy level of the atom • They are VERY important to bonding and reactions!

  21. GROUPS • Every element in the first column (Group 1) has one electron in its outer shell. Every element in the second column (Group 2) has two electrons in its outer shell. ETC. 2. Label the group #s and valence electrons

  22. Label Your PT

  23. Symbols on the PT 19 K 39.1 Atomic Number= number of protons

  24. Symbols on the PT 19 K 39.1 Symbol

  25. Symbols on the PT 19 K 39.1 Average Atomic Mass= average mass of the naturally occurring isotopes

  26. Let’s Label the PT • Oxidation Number = charge • Relates to how many electrons needed to become stable • To become stable an atom wants 8 electrons (THE OCTET RULE) • “Eight is great, except for hydrogen and helium, 2 will do”!

  27. Label Your PT

  28. Let’s Label the PT • Multivalent= elements with 2 or more possible charges +1 only = Ag +1, +2 = Cu, Hg +2, +3 = Cr, Ni, Fe, Co +2, +4 = Pb, Sn

  29. LabelYour PT

  30. Let’s Label the PT • Diatomic Molecules • Atoms that exist in nature as pairs • Only diatomic when ALONE! H2, O2, Cl2, I2, N2, F2, Br2

  31. LabelYour PT

  32. Let’s Label the PT • Metals, Nonmetals, & Metalloids

  33. Label Your PT

  34. Groups • Group 1: Alkali Metals • Most reactive metals • Do not occur in nature • Very soft • Explode in Water

  35. Groups • Group 2: Alkaline Earth Elements • Very reactive • Not found in nature

  36. Groups • Group 3-10: Transition Metals • Unreactive – used in coins and jewelry • Electrons they use to bond are in more than one energy level(MULTIVALENT) • Iron, Cobalt, and Nickel are Magnetic

  37. Groups • Metalloids • On the stair-step line • Properties of metals & non-metals • Semiconductors

  38. Groups • Group 17: Halogens • Most reactive non-metals • Exist as all three states of matter at room temperature • Compounds with them are called “salts”

  39. Groups • Group 18: Noble Gases • Contain 8 electrons in outer shell (oxidation # 0) = stable • Unreactive

  40. Groups • 57-71: Lanthanides • 89-103: Actinides • Most are synthetic, or man-made • Actually in Period 6 & 7 • Actinides are Radioactive

  41. Assignment Time… • Complete the Family Sort and the Crossword Puzzle. It is due next class!

  42. Wrap Up • Family Clicker Review

  43. Today… • Turn in: • Crossword/Family Sort – basket • Our Plan: • Crash Course Review • Clicker Review • Notes – Trends • Periodic Trends War • Homework (Write in Planner): • Nothing

  44. Quick Crash Course Review • 5 – 7 minutes • http://www.youtube.com/watch?v=0RRVV4Diomg

  45. Periodic Trends • Activity Series of Metals - Reactivity increases right to left and top to bottom • Most reactive = Fr

  46. Why? • The further to the left and down you go, the easier it is for electrons to be given or taken away
