2. If not, this is HOMEWORK due tomorrow!!!
Your cards should be TOTALLY FILLED IN by the time you leave class today!
If not, this is HOMEWORK due tomorrow!!!
(this needs to be done to do the next step in the project)
Also: WORK IN PENCIL & Draw dots SMALL/NEATLY
Periodic Table: pp

3. JUSTICE HAS BEEN SERVED!!!
Thank you for helping prove my innocence!

4. CLEAR OFF TABLES! (Folders & Binders) Get out your PERIODIC CARDS
Please WAIT FOR INSTRUCTIONS to begin the next steps on the project.
You will have plenty of time and I want to make sure you know what to do! 
You can work on your BOHR DIAGRAMS and LEWIS STRUCTURES.

5. Do this 1st if you don’t have this done!
USE THE KEY so you know what color to do each element.
Only color the small square in the upper L corner (not the whole card!)
Color LIGHTLY (so you can still read the info!)
2nd
3rd
Hint: Lay out all your cards BEFORE you glue them!

6. CLEAN UP
Put your PERIODIC TABLE on the counter in the stack for your CLASS PERIOD.
Put your INSTRUCTIONS SHEET in your FOLDER.
Pack folders.
Supplies back into basket.
Clean up any mess on the floor.

8. Helium He Neon Ne Argon Ar Hydrogen H Lithium Li Sodium Na
Which elements had complete outer shells? Give the name and symbol for each.
________________ _____ ________________ _____ ________________ _____
2. What do you notice about the location of these elements?
3. Which elements had only one valence electron? Give the name and symbol for each.
4. What do you notice about the location of these elements?
Helium He
Neon Ne
Argon Ar
The elements are in the same column at the far right side of the table.
Hydrogen H
Lithium Li
Sodium Na
The elements are in the same column at the far left side of the table.

9. Na Mg  Al  Si  P  S  Cl  Ar
5. What do you notice about the number of valence electrons as you move from left to right across a row or period in the periodic table?
Na Mg  Al  Si  P  S  Cl  Ar
6. What do you notice about the number of energy levels or shells as you move down a group or column in the periodic table? H  Li Na
Na – 1 Mg – Al – Si – 4
The number of valence electrons increases by one as you move across each row.
H – 1
Li – 2
Na - 3
The number of energy levels increases by one as you move down each column.

10. Boron Family - 3 valence electrons Halides - 7 valence electrons
7. Write the name of each family at the top of the columns on your periodic table using the following information.
Alkali Metals - 1 valence electron Nitrogen Family - 5 valence electrons
Alkaline Earth Metals - 2 valence electrons Oxygen Family - 6 valence electrons
Boron Family - 3 valence electrons Halides - 7 valence electrons
Carbon Family - 4 valence electrons Noble Gases - Complete outermost shell
Alkali Metals
Alkaline Earth Metals
Boron Family
Carbon Family
Nitrogen Family
Oxygen Family
Halides
Noble Gases
8. What do you notice about the location of the elements in each family?
The elements in each family are in the same columns.

11. ? 9. In what family would you classify hydrogen? Explain.
Alkali Metals
Alkaline Earth Metals
Boron Family
Carbon Family
Nitrogen Family
Oxygen Family
Halides
Noble Gases ?
9. In what family would you classify hydrogen? Explain.
Alkali Metals – Hydrogen has only one valence electron so it could be classified with the alkali metals. OR
Halides – Hydrogen only needs one more valence electron to fill its outer shell so it could be classified with the halides.

12. Barium = _____ Lead = _____ Xenon = _____ Potassium = _____
10. Predict the number of valence electrons for each element based on its location in the Periodic Table of Elements. You will need to use the table in your textbook.
Barium = _____ Lead = _____ Xenon = _____ Potassium = _____ 2 4 8 1
