Read each question carefully and provide the best answer. Remember the rules for naming ionic compounds!

Ionic compounds are formed when a metal atom transfers one or more electrons to a nonmetal atom, creating oppositely charged ions that attract each other. The image below illustrates the formation of an ionic bond.

Ionic Bond Formation

1. What type of bond is formed when electrons are transferred between atoms?

a

Covalent bond

b

Ionic bond

c

Metallic bond

d

Hydrogen bond

2. In the name 'sodium chloride', what is the name of the metal ion?

a

Chlorine

b

Chloride

c

Sodium

d

Sodide

3. The first part of an ionic compound name is the  , which keeps its original name.

4. The second part of an ionic compound name is the  , which changes its ending to -ide.

5. When naming ionic compounds, the   is always written first.

6. Name the following ionic compounds:

a) NaCl

b) MgO

c) CaCl₂

7. The compound KCl is named potassium chlorine.

T

True

F

False

8. In an ionic compound, the nonmetal's name always ends in -ide.

T

True

F

False

Match each ionic compound on the left with its correct name on the right.
