1. Chapter 10 The Periodic Table

2. Ch 10 Less. 1 Objective Learn about the History of the periodic table Get a general idea of how it is arranged Warm- Up Explain in your own words what the periodic table is.

3. The PT (periodic table) A table of repeating patterns These patterns help arrange elements in terms of physical and chemical changes

4. History-Father of PT

5. History - Moseley Mendeleev’s table had some problems- large gaps and some elements seemed to be in the wrong order. Moseley rearranged the PT in terms of increasing atomic number

8. Activity You have been provided a blank PT. – Label the 7 periods – Label the 18 groups – Use LIGHT colors and create a key to color in the metals, non-metals and metalloids

9. Exit Ticket What PHYSICAL property did Mendeleev use to place the elements in rows on the PT? Name a physical property that repeats on the PT. (think about physical properties, you may have to look back to Ch 7) What determines where elements are placed on the PT today?

10. Ch 10 Less. 2 Objective Learn the metals on the PT Warm- Up Describe a metal in your own words. – Do they conduct heat, how about electricity. Provide examples

11. Metallic Properties Luster (reflects light) Conductivity (conducts heat and electricity) Ductile (able to be pulled into a wire) Malleability (rolled or hammered into sheets)

15. Activity You have been provided a blank PT. – Label the 7 periods – Label the 18 groups – Use LIGHT colors and create a key to color in the metals, non-metals and metalloids – Label the following names: alkali metals, alkali earth metals, transition metals, lanthanides and actinides – Answer the following: why are the lanthanides and actinides at the bottom of the table? And which element is considered to have the most metallic properties.

16. Exit Ticket Page 360 1-7

17. Lab Objective Complete Density Lab Warm-Up If a rock is considered matter and matter takes up volume, then what happens to the water level of a cup when a rock is dropped in? How could I determine how much the water level rose?

18. -Units - How to use it

19. -units -water displacement -meniscus

20. Exit Ticket-Lab Included in Lab

21. Ch 10 Less. 3 Objective Learn the non-metals and metalloids on the PT Warm- Up Name one non-metals Do non-metals conduct electricity? So, what is Hydrogen? Is it a metal or a non-metal. Think about what you know and where it is located on the PT.

22. Non Metals Gas at room temperature Not lustrous Does not conduct heat or electricity Good insulator

25. Metalloids Semiconductors of electricity at HIGH temps not low temps

27. Activity You have been provided a blank PT. – Label the 7 periods – Label the 18 groups – Use LIGHT colors and create a key to color in the metals, non-metals and metalloids – Label the following names: alkali metals, alkali earth metals, transition metals, lanthanides and actinides – Answer the following: why are the lanthanides and actinides at the bottom of the table? And which element is considered to have the most metallic properties. – Label groups 14-16 as non metals – Name the halogens and the noble gases – Fill in the symbol for the elements

28. Exit Ticket HW Pg 369 1-6 and 9

29. Ch 10 Objective Review Ch 10 Warm- Up What is a metalloid? What is a semiconductor How are semiconductors the same as metals? How are they different?

30. Agenda Check HW Handout PT WS review of PT

31. Exit Ticket HW: Pg 374 1-9

32. Ch 10-day 6 Objective Trends on the PT – Atomic radii and electronegativity (you will add these to your PT) Warm- Up Contrast Aluminum and Nitrogen. Show why aluminum is a metal and nitrogen is not.

34. Atomic Radii Trend Questions Circle the atom in each pair that has the largest atomic radius. – Al or B – Na or Al – S or O – O or F – Br or Cl – Mg or Ca

36. Electronegativity Trend Questions Circle the atom in each pair that has the greater electronegativity. – Ca or Ga – Br or As – Li or O – Ba or Sr – Cl or S

37. Exit Ticket Why is mercury the only metal to have been used in thermometers? (think about its state of matter at room temperature)

38. Ch 10 Objective Review Ch 10 Warm- Up Create the foldable on Page 373 to help review for the test Review Stand Test Prac. Pg 376-377
