Read the Review Skills section. If there is any skill mentioned that you have not yet mastered,
review the material on that topic before reading the present chapter.
Read the chapter quickly before the lecture that describes it.
Attend class meetings, take notes, and participate in class discussions.
Work the Chapter Exercises, perhaps using the Chapter Examples as guides.
Study the Chapter Glossary.
Study all of the Chapter 3 Objectives. You might want to write a
description of how you will meet each objective. (Although it is best to master
all of the objectives, the following objectives are especially important because
they pertain to skills that you will need while studying other chapters of this
text: 3, 4, 8, 9, 13‑16, 21-28, 30, 31, 34, 35, and 37.)
Reread Sample Study Sheet 3.1: Classification of Matter and
decide whether you will use it or some variation on it to complete the task it describes.
Memorize the following. Be sure to check with your instructor to determine how much you
are expected to know of the following.
The usual numbers of covalent bonds and lone pairs for the nonmetallic elements.
C - 4 bonds and no lone pairs
N, P - 3 bonds and 1 lone pair
O, S, Se - 2 bonds and 2 lone pairs
F, Cl, Br, I - 1 bond and 3 lone pairs
H - 1 bond and no lone pairs
