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 Bonding

Ionic Bonding
Chemical Bonding

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.

Covalent Bonding

Covalent Bonds  
Molecular Structures - Physical Properties (Note: "molecular" = "covalent")
Chemical Bonding

Bonding by Analogy: Dog-Bone Bonds

Use the Bonding Comparison Chart to summarize your answers to questions 1-4.

  1. What types of atoms typically form covalent bonds?

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

  3. What are the typical properties of covalent 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 covalent bonding.  Resize the image to make it small enough to fit.

  5. First, read about the difference between polar and nonpolar covalent bonds.  Then, review the Dog-Bone analogy.  On the worksheet, summarize the difference between ionic, polar covalent, and nonpolar covalent bonds using the Dog-Bone analogy.  Be sure to describe electronegativity and the role it plays in determining which type of bond is formed.

Metallic Bonding

Metallic Bonding - Bonding in Metals
Metallic Bonding
Metallic Structures - Physical Properties of Metals

Use the Bonding Comparison Chart to summarize your answers.

  1. What types of atoms typically form metallic bonds?

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

  3. What are the typical properties of metallic 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 metallic bonding.  Resize the image to make it small enough to fit.
