1. Do Now Wednesday NB 17 bottom (I know this is an odd place!!) 1.What is the difference between a mixture and a compound? 2.What type of mixture is Kool-Aid? Why? 3.What type of mixture is trail mix? Why? Agenda: -Finish Compound/Mixtures -Periodic Table Notes – NB 19 -Periodic Table Foldable - NB 18 -Stations?

2. Announcements  Grades are updated. Thursday is last day to turn anything in to me.  Books go home today… Keep it at home until May. ($55 so don’t lose!)  Study Guide Pages -> 3.1D,3.2D, 3.3D  Chapter Reviews -> pgs 35D, 63D, 101D  Extra credit -> Questions at the end of the sections in the chemistry unit.  Each full chapter is worth  Friday – Kidney procedure at hospital -> sub  Turn work in! Last day of quarter  Best Behavior!  If sub has to speak to you… you will be suspended. Don’t do it!

3. Behavior  We need to step it up!!  I will only talk to you twice  Call/referral depending on the offense  If you walk out of my room… you will not return  Classwork grade – 125 points/ week  Participation grade – 125 points/week  Each day is worth 25 pts! Do not lose them!!!

4. Some questions we need answers for…. 1.Where are metals located on the table? Nonmetals? Metalloids? 2.What are some differences between metals and nonmetals? 3.What shape do metalloids form on the periodic table?

5. Objectives NB 19  Describe the design of the modern periodic table.  Discuss how families contain elements with similar properties.  Explain how properties of elements vary across a horizontal row, or period.  Compare the properties of metals, nonmetals, and metalloids.

6. Vocabulary  Group  Family  Period  Metal  Nonmetal  Metalloid  Valence Electrons

7. Periodic Table Design

8. Group (Family)  Columns (18)  Have similar properties Li, Na, and K are all soft, white, shiny metals and are highly reactive Li, Na, and K are all soft, white, shiny metals and are highly reactive Same number of valence electrons Same number of valence electrons

9. Valence electrons are electrons in the outer most energy level (electron shell)

10. Check-Up 1.Where are electrons located in the atom? 2.Why are groups also called families? (Hint: think of what makes you part of a family)

11. Period  Rows (7) Rare-Earth Elements are part of row 6 & 7 Rare-Earth Elements are part of row 6 & 7 Not alike in Not alike inproperties

12. Element Key Oxygen 8 O 15.999

13. Metals  Elements left of the zigzag line are metals or metal- like

14. Metals  Physical Properties  Solids at 25 0 C  Luster (shine)  Conductors of heat and electricity  High Density  Fairly high melting point  Ductile (into wire)  Malleable (into thin sheets)

15. Check-Up 1.What is an example of a metal? Why do you think this is a metal? (use the terms we just learned) 2.Where are metals located on the periodic table?

16. Nonmetals  Located to the right of the zigzag line.

17. Nonmetals  Physical Properties  Most are gases at 25 o C  Some are brittle solids.  No Luster, Dull  Not conductors of heat and electricity  Low densities  Low melting points

18. Check- Up 1.What is an example of a nonmetal? Why do you think this is a nonmetal? (use the terms we just learned) 2.Where are nonmetals located on the periodic table?

19. Metalloids  Touching the zigzag line  Have properties of both metals and nonmetals.  Solids that can be shiny or dull.

20. Check-Up 1.What is an example of a metalloid? Why do you think this is a metalloid? (use the terms we just learned) 2.Where are metalloid located on the periodic table?

21. Exit Ticket –> Bottom of Notes! Ready for foldable??? 1. List 3 Properties of metals. 2. List 3 properties of non-metals. 3. Where are the metals located on the periodic table? 4. Where are the non-metals located on the periodic table? 5. Where are the metalloids located on the periodic table?

22. Periodic Table foldable NB 18  Each person gets 6 mini-PTs  Tape them as flaps (landscape)  We will take notes underneath!  We will color/label as we go  Label them 1.Alkaline Metals 2.Alkaline Earth Metals 3.Transition Metals 4.Poor Metals 5.Metalloids 6.Halogens 7.Nobel Gases 8.Rare Earth Metals 1. 2. 3. 4. 5. 6.7.8.
