  1. Breaking the code Periodic Table Fundamentals

  2. Chem catalyst • Using the card sort chart or your cards: • Look back at Mendeleev’s chart (pg 29). Where did he place Cu? (Cu’s atomic weight is 63,it reacts very slowly with water, is a shiny metal) • Where would you place Cu in your card table? Is it the same as Mendeleev? Explain your answer

  3. Unit 1 • Investigation II

  4. The Big Question • How can you predict properties of elements using a periodic table? Unit 1 • Investigation II

  5. You will be able to: • Interpret some of the information given in the periodic table. Unit 1 • Investigation II

  6. Connection between Card table and the modern periodic table

  7. Notes (cont.) Unit 1 • Investigation II

  8. Notes (cont.) (cont.) Unit 1 • Investigation II

  9. Notes (cont.) (cont.) Unit 1 • Investigation II

  10. Notes (cont.) • The elements in the middle of the table are referred to as the transition elements, or the transition metals. Unit 1 • Investigation II

  11. Activity Purpose: • This lesson will help to identify many of the patterns of element characteristics that are contained in the periodic table of the elements. • This lesson also provides names for different collections of elements with similar characteristics, and the manner of naming a specific spot in the periodic table (cont.) Unit 1 • Investigation II

  12. Activity • Students will be broken up into groups of 3 • Each student needs a copy of a periodic table and their comp book • Spaced around the room is information on a number of topics. • Each group divides the topics amongst themselves, and gathers information on those topics by moving around the room to papers with their topics • Students then report back to their groups to share and explain their information to the other members • Information on groups, families, periods must be shown on the copy of the periodic table through the use of color

  13. Topics • Which Elements are liquid at room temp? • Which elements are gases at room temp? • Which elements are defined as a metal, what are their common characteristics? • Which elements are defined as a non-metal, what are their common characteristics? • Which elements are defined as a metalloid, what are their common characteristics

  14. Topics 6. What on the periodic table, is identified by the period, and do any periods have a name? 7. What on the periodic table is identified by the group number, and what is their number range? 8. Who are the transition metals, and what are their common characteristics? 9. Who are the Alkali metals and what are their common characteristics? 10. Who are the Halogens and what are their common characteristics?

  15. Topics 11. Who are the Noble gases and what are their common characteristics? 12. Who are the Alkaline Earth Metals and how reactive are they? • Who are the Lanthanides, and what is their group number? • Who are the Actinides, and which are artificially created • Which elements are radioactive in all forms?

  16. Activity • After all members of the group have placed the info in their composition books and colored their charts, Each group will complete the Lab questions.

  17. (cont.) Unit 1 • Investigation II

  18. Answer the questions on page 33-34 in lab book Write each question and your response. • Include the “making sense” question and “if you finish early” • Leave some space for additions or alterations to your answer

  19. Question #1 • Using the card sort poster; • Make a list of as many patterns as you can find from the card sort poster that occur horizontally

  20. Size of circle decreases left to right

  21. Question #2 • Make a list of as many trends as you can find from the card sort poster that occur vertically.

  22. Color • Atomic mass increases

  23. Question #3 • Which trend or pattern does each of the following diagrams describe? Explain

  24. Down arrow and up arrow: REACTIVITY, the darker the hue the more reactive • Just Down Arrow: SOFTNESS, Circle Size • Arrow left to right: # of Spikes, atomic mass

  25. Question #4 • Where are the metals located on the periodic table? Explain

  26. Towards the left of the table in general

  27. Question #5 • Is copper, Cu, a metal or nonmetal? Explain your thinking

  28. Cu is a metal • Exists somewhere between Ca and Ga, both metals

  29. Question #6 • The elements inserted into the card sort from Mendeleyev’s table are called transition elements. Do you expect the elements to be solids, liquids or gases? Explain.

  30. Most likely solids all of column 2 and most of column 3 are solids

  31. Question #7 • Where are most of the gases located on the periodic table?

  32. Most gases are on the upper right of chart

  33. Question #8 • Is thallium, Tl, a solid, liquid, or gas

  34. solid

  35. Question #9 • In what areas do you find the most highly reactive elements?

  36. Lower left (IA) and Upper Right (VII A)

  37. Question #10 • How would you expect cesium, Cs to react with water? Explain

  38. More explosively than rubidium

  39. Question #11 • Find the element with the atomic weight 137.3. If there was a card for this element what would it probably say in the lower left corner?

  40. Ba Barium • Reacts explosively with water

  41. Question #12 • Place the following in order of most reactive to least reactive. • Rubidium, Rb • Neon, Ne • Silicon, Si • Calcium, Ca

  42. Rb • Ca • Si • Ne

  43. Question #13 • Elements combine to form compounds. For the compound listed, specify whether two metals, a metal and a nonmetal, or two nonmetals were combined • NaCl

  44. Question #14 • Elements combine to form compounds. For the compound listed, specify whether metals, metals and a nonmetals, or nonmetals were combined • CH4O2

  45. Question #15 • Elements combine to form compounds. For the compound listed, specify whether two metals, a metal and a nonmetal, or two nonmetals were combined • CuSn

  46. Question #16 • The elements copper and gold are both relatively unreactive. It is easy to bend and shape both metals. Is the similarity in their properties consistent with their locations on the periodic table? Explain

  47. They are in the same column (group)

  48. Question #17 • Create a card for the element lead, Pb • Information in all four corners, atomic mass number and circle with sticks

  49. Lead Soft, Silver gray, solid metal Pb Found in PbH4 Reacts slowly with oxygen

  50. Making Sense • The elements copper and gold are both relatively unreactive. It is easy to bend and shape both metals. Both are used to make coins and jewelry. Is the similarity in their properties consistent with their locations on the periodic table? Explain why or why not. Unit 1 • Investigation II
