Chapter 1. Discussion Questions

1.1 Discussion Questions

1. Types of bonds in solids: There are four main types of bonding in solids. Each type has a characteristic arrangement of the valence electrons in a solid.

List 6 examples for each of the four types of bonding.
For each type of bonding, explain what holds the atoms together.
Which of the bonding models are found in elemental substances? Explain, using examples.

For small group or whole class discussion

Can be projected by the instructor or printed

1.2 Discussion Questions

2. Bonding and properties: All solids consist of a large collection of atoms arranged in three dimensions. Imagine how valence electrons in specific locations hold all those atoms together. The properties of solids are directly related to the locations of the valence electrons.

Explain how the location of the electrons in a metallic substance might account for the flexibility and softness of copper metal.
For each type of bonding, explain what holds the atoms together.
Explain how the location of the electrons in a covalent network solid might account for the incredible hardness of a diamond.
How does the model of molecular covalent bonding account for the fact that these substances are often gases or liquids?
Some substances made entirely of non-metal atoms are soluble in water, while others are not. Use the bonding models to explain why.
Both sugar and salt dissolve in water, but they are bonded differently. Use the models to explain how these two substances might be different once they dissolve.
