1. Turn to the back cover of your chemistry textbook. Color code the metals, metalloids and nonmetals on
your personal periodic table.
2. Most of the elements on the periodic table are ____________ (metals, metalloids, nonmetals).
3. Metallic properties ___________________ as you move from the left to right on the periodic table.
Explain the reasoning for your answer.
4. Metals tend to lose electrons. Use this information to predict whether metallic properties increase or
decrease as you move down a group on the periodic table. Metallic properties _________________ as
you move down a group on the periodic table.
5. What does diatomic mean?
6. The seven diatomics are?
7. Color code the seven diatomics on your personal periodic table.
8. What does metalloid mean?
9. How many metalloids are on the periodic table?
10. Where are the metalloids located on the periodic table?
11. If the period number indicates how many energy shells an element possesses, how many total energy
shells are possible for an element?
12. Find the definition for the “octet rule” on page 168 of your textbook. Write the definition here.
13. Which electrons are valence electrons? (page 140)
14. According to the octet rule, the “perfect” number of valence electrons that elements “desire” is _____.
15. If the group number indicates the number of valence electrons an element possesses, which elements
already possess the desired “8” electrons? (disregard the “transition metals” in the middle of the periodic table)
16. What does the word “inert” mean?
17. Which elements would most likely be considered “inert”? Explain the reasoning for your answer.
