Ionic Bonding

Chemical Bonding
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.

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.

CONCLUSION

You have had the opportunity to explore the key aspects of ionic, covalent, and metallic bonding.   Now, let's put your newfound knowledge to use!

1. Use your Come Together Worksheet to complete the following online quiz.  If your score is lower than 8/10, you need to review the topics you missed.

2. Choose one of the following products to demonstrate what you have learned.
   

• STORY - Choose one type of bonding and write “A Day in the Life of an Atom” story describing what it's like to be an atom that forms your chosen bond type.  The story should incorporate at least 5 properties.

• COMIC STRIP - Choose one type of bonding and write a comic strip with 3+ frames. The comic should incorporate at least 3 properties.

• SINGLE-FRAME CARTOON - Draw a single-frame cartoon for each type of bonding.  Each cartoon should incorporate at least one key property.
