1. Intro to the Periodic Table

2. Evaluation/ Assessment
Objective
Today I will be able to:
Identify the properties of the families on the periodic table
Evaluation/ Assessment
Informal assessment – Listening to group interactions and discussions as they complete the analyzing the periodic trends graphing activity
Formal Assessment – Analyzing student responses to the exit ticket and graphs

3. Lesson Sequence Warm – Up Engage/Explore: Coloring the Periodic Table
Explain: Introduction to the periodic table notes and video clips
Elaborate: identify the trends in noble gases and across periods
Informal assessment as students predict trends
Evaluate: Exit ticket

4. Warm - Up
A laser emits light of frequency 4.74 x 1014 Hz. What is the wavelength of the light in nm?
What is the energy, in Joules, of this laser?

5. Objective Today I will be able to:
Identify the properties of the families on the periodic table
Review for the upcoming Chapter 4 exam

7. Agenda Warm – Up Coloring the Periodic Table
Introduction to the Periodic Table Notes
Exit ticket

8. Coloring the Periodic Table Activity
Follow Mr. Klotz’s directions to color the periodic table
Discuss the importance of order for the periodic table. What are some ways we can order it already?

9. Intro to the Periodic Table Notes

10. There are two ways to number the periodic table:

13. Periodic Table Structure
Vertical groups are called families or groups, and have similar properties
- There are 18 groups
Horizontal rows are called periods
- There are 7 periods
Elements are classified into three types – metals, non-metals, and metalloids (sometimes called semi-metals)

14. Metals Found to the left of the “zig-zag” line on the Periodic Table
Properties of Metals
- Luster – shine
- Malleable – can be hammered into sheets
- Ductile – can be drawn into a wire
- Good conductors – allow heat and electricity to pass through

15. Classification of Metals
Alkali Metals (Group 1, except H) – water solutions are alkaline (basic)
Alkaline Earth Metals (Group 2) – extracted from earth’s minerals
Together, they are called the Active Metals

16. Classification of Metals
Transition Metals (Found in periods 4-7, in the middle of the table) – mostly found in compounds
Inner Transition (Rare Earth) Metals
- Lanthanides – starting with La, 4f sublevel being filled
- Actinides – starting with Ac, 5f sublevel is being filled

17. Non-Metals
Non-metals and noble gases are found to the right of the “zig-zag” line
Their properties are the opposite of metals

18. Classification of Non-Metals
Halogens (Group 17) – highly reactive, all form salts by reacting big time with alkali metals, as well as other metals – also reacts with non-metals
Noble Gases (Group 18) – least reactive, most stable

19. Metalloids (Semi-Metals)
Most of the elements touching the zig-zag line
B, Si, Ge, As, Sb, Te, and At
They have similar properties of metals and some properties of non-metals

20. Chapter 4 Review Problems
Complete the review for Homework due Monday!

21. Exit Ticket What is the most stable family on the periodic table?
Why is this family the most stable?
What families contain the most reactive elements on the periodic table?
