Periodic Table Basics
Use your abridged PToE to analyze the PToE
1.
What surprises you about your abridged periodic table?
2.
Which elements had complete outer shells? List them.
3.
Where are each of these elements located?
4.
Which elements have only 1 electron in its outer shell? List them.
5.
Where are these elements located?
6.
Which elements have only two shells with electrons located in them?
7.
Where are these elements located?
8.
What do you notice about the number of electrons in the outer shell as you move from left to right in row number 3? (Na
Mg  Al  Si  P  S  Cl  Ar)
9.
What do you notice about the number of shells as you move down a group/column? (HLiNa)
Valence electrons: A fancy
term for the electrons found
in the outer shell – these are
the important ones because
they are involved with forming
bonds
10. Cut out and glue the name of each family at the top of the columns on your periodic table using
the following information:
Alkali Metals - 1 valence electron
Alkaline Earth Metals - 2 valence electrons
Boron Family - 3 valence electrons
Carbon Family - 4 valence electrons
Nitrogen Family - 5 valence electrons
Oxygen Family - 6 valence electrons
Halides - 7 valence electrons
Noble Gases - Complete outer shells
11. What do you notice about the location of the elements in each family?
12. In what family would you classify hydrogen? Explain your choice.
Alkali Metals
13. In what family would each of these elements be classified?
Nitrogen Family
Radium - ________________________
Tin - ________________________
Iodine - ________________________ Cesium - ________________________
Alkaline Earth Metal
Oxygen Family
14. Predict the number of valence electrons for each element based on its location in the Periodic Table of
Elements.
Boron Family
You will need to use the table in a textbook.
Halides
Carbon Family
Barium = _____ Lead = _____ Bismuth = _____ Potassium = _____
15. Using the PURPLE PHYSICAL SCIENCE TEXTBOOK, FIND OUT WHAT “LEWIS DOT” IS AND ADD THAT TO
EACH OF YOUR CARDS….IN THE BOTTOM RIGHT CORNER OF THE CARD
