INTRODUCTION

Much like people, most atoms don't like to live solitary existences.  They need to COME TOGETHER with other atoms to lead more stable, happier lives.  This process of coming together is called chemical bonding.  Through completing the following Internet Activities, you will learn the characteristics of three types of bonding - covalent, ionic, and metallic.  Use this worksheet to record your answers to the questions below.  KEEP YOUR DESCRIPTIONS SHORT AND SIMPLE.  If you need additional help in defining chemistry related terms, use this Chemistry Dictionary.

Ionic Bonds

Use the Bonding Comparison Chart to summarize your answers.

  1. What types of atoms typically form ionic bonds?

  2. How are ionic bonds formed and what type of structure do they create?

  3. What are the typical properties of ionic substances?  Include the following: physical state, melting point, solubility in water, electrical conductivity, and any other properties you'd like to include.

  4. Insert an image into the chart that you feel best represents ionic bonding.  Resize the image to make it small enough to fit.
