1. Daily TAKS Connection: Periodic Table
IPC(7): The student knows relationships exist between properties of matter and its components. The student is expected to:
(D) relate the chemical behavior of an element. including bonding, to its placement on the periodic table.

2. How to make the foldable:
Construct a folded book foldable and title “Periodic Table”
Materials:
Foldable handout (2 pages)
Scissors
Pen
Colored pencils/crayons
Periodic Table (needed daily for note-taking activities)
Instructions:
Hamburger fold the foldable handouts
Cut 2 cm slits from the edges of the fold of the handout that has page 2 (as marked)
Cut along the fold line of the other sheet of paper beginning and ending about 2 cm from each end (as marked).
Burrito fold and insert paper from step 2 into the hole and open, forming a book.

3. Page 1: Record the following on page 1 of your foldable:
number of protons is the same as the atomic number; used to ID an element
The element modeled is Beryllium; has 4 protons.
Student Task: ID this element

4. Page 2: Record the following notes on page 2 of your foldable
“groups” or “families” are the columns on the Periodic Table
elements in the same group have similar physical and chemical properties

5. Page 3: Record the following notes on page 3 of your foldable
Group 18 are called “noble gases”
8 valence electrons (stable octet)
noble gases are resistant to forming compounds
Student Task: Color and label the noble gases on the drawing on page 3 of your foldable.

6. Page 4: Ionic Bonds: when metals form bonds with nonmetals
Record the following notes on page 4 of your foldable
Ionic Bonds:
when metals form bonds with nonmetals
Halogens, group 17 elements, form ionic compounds (salts) called halides
Metals
Nonmetals
Left of bold line (staircase)
Right of bold line (staircase)
Lose electrons when bonding
Gain electrons when bonding
Form ca+ions
Form anions
Positive ions (positive oxidation numbers)
Negative ions (negative oxidation numbers)

Student Task
On the top drawing on page 5 of your foldable, shade the metals one color and the nonmetals a different color.
On bottom drawing on page 5 of your foldable, shade the halogen group.

8. Page 6: How to determine oxidation numbers
Record the following notes on page 6 of your foldable
How to determine oxidation numbers
Find the group number (roman numeral) for the element (located at the top of the group).
Determine if the element is a metal or a nonmetal.
If it is a metal, the roman numeral value from the group number is the positive value of the oxidation number.
Example: Hydrogen is in group IA; therefore the oxidation number is +1 and the cation is written H1+. OR
If it is a nonmetal, subtract the roman numeral value from eight. Assign a negative sign to the oxidation number.
Example: F is in group VIIA; 8 – 7 = 1; therefore the oxidation number is -1 and the anion is written F1-.

9. Page 7:
Record the following notes on the top of page 7 of your foldable
Criss-Cross Method for writing ionic compound formulas
Rule: Value of oxidation # of cation becomes the subscript of the anion
Rule: Value of oxidation # of anion becomes the subscript of the cation
Ca2+
Cl1-
Ca1
Cl2
CaCl2

10. Page 7:
Record the following notes on the bottom of page 7 of your foldable
Covalent Bonds
Non-metals form bonds with non-metals
Elements share electrons
Examples: CO2, CH4
Carbon, Oxygen, and Hydrogen are all nonmetals
