Reading Focus Questions

September 8

Section 2.8

1.    List three physical properties shared by metals.  Identify the one chemical property shared by metals.

2.    Identify two chemical properties shared by nonmetals.  (Remember, chemical properties have to do with what the electrons are doing.)

3.    Discuss the relevance of "groups" in the periodic table.

Section 12.12

4.    What was the original logic for the arrangement of elements on the periodic table?  Does this logic still hold?

Section 13.2

5.    What is the definition of electronegativity?

6.    Skim the next two paragraphs as your interest requires.  Resume careful reading with the paragraph that starts "Electronegativity values have been determined by this process . . ."

7.    What kind of bond would you expect to form between carbon and oxygen?  Between hydrogen and oxygen?  Between two oxygens?

8.    As is true for many combinations of a metal and a halogen, sodium and chlorine form ionic bonds. What kind of bond would you expect between arsenic and bromine?  [Compare the differences in electronegativities as reported in Figure 13.3.  Note that carbon and oxygen form a polar covalent bond.]

9.    What is the trend in atomic radii going down the periodic table?

10.    What is the trend in atomic radii going across the periodic table?
