1. Name the type of structures shown in the left-hand column of Model 1.

2. Examine the drawings in Model 1.

a. What does a solid line between two element symbols represent in the drawings of the molecules?

b. What subatomic particles (protons, neutrons or electrons) make up these solid lines?

c. What does a pair of dots represent in the drawing of the molecules?

d. What subatomic particle (protons, neutrons or electrons) makes up each dot?

3. In the English language, what does the word “domain” mean? (Your group must come to consen-

sus on this question.)

4. Which molecules in Model 1 have four electron domains? Circle or highlight the four electron

domains in the Lewis structure for each molecule that you identified.

5. Which molecules in Model 1 have two electron domains? Circle or highlight the two electron

domains in the Lewis structure for each molecule that you identified.

6. Which molecule in Model 1 has three electron domains? Circle or highlight the three electron

domains in the Lewis structure for the molecule that you identified.

7. When determining the number of electron domains in a Lewis structure, which of the following

should you count? Find evidence from Model 1 to support your answers.

a. Bonds on the center atom

b. Lone pairs on the center atom

c. Total number of atoms in the molecule

d. Lone pairs on peripheral atoms

8. When determining the number of electron domains in a Lewis structure, do you count double

bonds as one domain or two domains? Find evidence to support your answer from Model 1.
