• Compare and explain the properties of substances resulting from different types of bonding.
• List the properties of network solids.
• Describe and compare the structures and bonding in the three allotropes of carbon.
• Describe the structure and bonding in silicon and silicon dioxide.
• List examples of molecular solids.
• Explain why some larger nonpolar molecular solids are solid at room temperature.
