More Bond Types

Answer the following questions about various types.

Part 1: Metallic Bonds (Complete in your notebook)

Basis: Metallic bonding occurs within a metal.

• Watch the following animations that represent metallic bonding: Animation 1 and Animation 2

• Sketch a diagram to represent the animation.

• Write an explanation of your diagram

Visit the following site to read about properties of metals: Properties of metals

• List the 8 properties of metals

• Choose 3 properties and explain why metals have these properties.

Part 2: Networking Covalent Bonding (Complete in your notebook)

Use the internet to answer the following questions about networking covalent bonding.

• What is networking covalent bonding?

• Diamonds are an example of networking covalent. What elements make up a diamond and draw a picture to represent it.

• Quartz also has networking covalent bonding. What elements make up quartz, what is its formula, and draw a picture to represent it.

• We have discussed solubility, melting point, and conductivity of various bond types. Without using the internet discuss the solubility, melting point, and conductivity of networking covalent bonds (think about why things conduct, have high or low melting points, and how know if something is soluble).

Part 3: Comparing Different Bond Types (Complete in your lab book)

Watch the video animation of the melting of ice, sodium chloride, and diamond then answer the following questions.

• What is being broken to cause ice to melt?

• What is being broken when sodium chloride melts?

• What is being broken when a diamond melts?

• Which of these are chemical bonds?

• Which of these are intermolecular forces?

• Which is the weakest (easiest to break)?

• What evidence supports this?

We have now covered all types of bonding: Covalent, Ionic, Metallic, and Networking.

• Draw a diagram to represent a solid sample of sulfur tetrafluoride. You diagram should include multiple molecules. Be neat!! Label the forces and bonds within your diagram. Next to the diagram, identify if it has a high or low melting point, if it can conduct, and if it is soluble in water.

• Draw a diagram to represent a solid sample of calcium oxide. You diagram should include multiple ions. Be neat!! Label the forces and bonds within your diagram. Next to the diagram, identify if it has a high or low melting point, if it can conduct, and if it is soluble in water.

• Draw a diagram to represent a solid sample of copper. You diagram should include multiple ions. Be neat!! Label the forces and bonds within your diagram. Next to the diagram, identify if it has a high or low melting point, if it can conduct, and if it is soluble in water.

• Draw a diagram to represent a sample of calcium oxide dissolved in water. You diagram should include multiple molecules and ions. Be neat!! Label the forces and bonds within your diagram.
