2. Catalyst 1. What are the trends for ionization energy on the Periodic Table? 2. Sort from lowest to highest IE: C, F, O 3. Sort from highest to lowest IE: Mg, Ca, Sr End

3. Quiz You have 20 minutes to complete the quiz This should be done without notes and should be completed silently.

4. Homework Review and Exit Slip Solutions

5. Exit Ticket 1.Draw the Bohr structure for Phosphorus 2.How many electrons must it gain/lose to satisfy the Octet Rule? What will the charge of its ion be? GAIN 3 e - ’s to become P 3- (anion) 3.What is wrong with the drawing below?

6. Fire!

7. Justify – TPS Why did sodium and magnesium produce very different results when they were lit on fire?

8. Lecture 1.5 – Metals, Nonmetals, Semimetals and Periodic Groups

9. Today’s Learning Targets LT 1.5 – I can identify an element as being an alkali metal, alkaline earth metal, transition metal, halogen, or Noble Gas. I can explain how electrons lead to these properties. LT 1.6 – I can identify an element as being a metal, non-metal, or semimetal.

10. Essential Point Elements in the same group have similar properties because they have the same number of valence electrons.

11. Alkali Metals Group 1A or Group 1 1 valence electron Highly reactive with water. Cannot find these elements on their own in the world.

13. Alkaline Earth Metals Group 2A or 2 2 valence electrons Highly reactive, but not as reactive as Alkali Metals

15. Halogens Group 7A or 17 7 valence electrons This is the most reactive group on the Periodic Table because it only needs to get 1 electron

17. Noble Gases Group 8A or 18 8 valence electrons Non-reactive It already has a full octet, so there is no need to react.

19. Transition Metals Groups 3 through 12 They have the typical properties of metals (conductor, malleable, etc.)

21. SUMMARIZE

22. The Magic of Cell Phones

23. Justify – TPS What properties of the SIM card do you think allows for it to store so much information?

24. Metals, Non-metals, and Semimetals

25. Metals – Common Characteristics Shiny Solids at room temperature Metals are malleable – Malleable - Able to be hammered/pressed permanently out Metals are good conductors of heat or electricity – Conduct –Heat or electricity can flow through a given material.

26. Non-Metals – Common Characteristics Dull Gases at room temperature Not malleable Poor conductors of heat and electricity, so we call them insulators. – Insulators – Substances that resist the flow of heat or electricity.

27. Semi-Metals – Common Characteristics A select group of elements that have characteristics of both metals and non-metals. Look metallic, but are brittle. They are neither good nor bad conductors or insulators, so we call them semi-conductors.

29. Locating On the Periodic Table The “staircase” separates metals from non-metals on the Periodic Table Elements to the left of the staircase are metals Elements to the right of the staircase are non-metals Elements that touch the staircase (except aluminum) are semimetals.

30. EXCEPTION TO THE RULE! Hydrogen is located to the left of the staircase Hydrogen is a non-metal.

31. SUMMARIZE

32. What Group Does It Belong In? With your partner, sort the card that you were handed into the category of metal, non-metal, or semimetal. Try to do this without your notes!

33. Color By Number With the Periodic Table you were handed, use colors to label the following groups: 1.Alkali Metals 2.Alkaline Earth Metals 3.Transition Metals 4.Halogens 5.Noble Gases 6.Number of valence electrons for groups 1A – 8A (skip the transition metals)

34. Exit Ticket 1.Sodium belongs to what group on the Periodic Table? 2.Arsenic is a metal, non-metal, or semimetal? 3.A student states that fluorine is a metal that is part of the noble gas family. What is wrong with this statement? 4.Why do all alkali metals demonstrate a similar reactivity?

35. Rate Yourself Based on the exit ticket and your current level of understanding, rate yourself 1 – 4 on LT 1.5 and 1.6

37. Closing Time Homework 1.4 – Metals, Nonmetals, Semimetals, and Periodic Groups due Wednesday
