Atoms Unite!
Let’s Make a Bond WebQuest
Introduction
In this activity you will learn about different types of chemical bonds and how they are formed. You will also
learn why some atoms bond with other atoms and why some do not bond. Complete the webquest to learn
about chemical bonding.
SECTION 1: Introduction to Bonding
Resource #1
1. What is a chemical bond?
2. Why do most atoms form chemical bonds?
Resource #2
3. Which subatomic particles participate in chemical bonding?
4. Explain how these subatomic particles interact to form bonds.
SECTION 2: Types of Chemical Bonds
Resource #3
5. Atoms can react with one another to form new substances called _________________________. The
resulting compound is unique both ________________ and ________________ from its parent atoms.
6. There are two main types of chemical bonding;____________ bonding and _______________bonding.
7. Ionic Bonds:
a. What is an ionic bond?
b. How are ionic bonds formed?
c. Give one example of an ionic bond.
8. This website explains the reaction between sodium and chlorine to produce sodium chloride. Read the
information and (1) write a summary and (2) sketch an illustration which shows how sodium and chlorine
bond with each other.
