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

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.

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 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

55. Wrap-Up
Elements in each column of the periodic table have similar properties.
We can predict the characteristics of a missing element based on the qualities of the elements found adjacent to it in a periodic table.
