Chapter 6 The Structure of Atoms INSTRUCTOR’S NOTES This chapter and the next one (Chapter 7) are aimed at giving students a firm foundation for understanding of the key theories of chemistry. Therefore, we devote a total of about 9 lectures to these chapters, with much of that time devoted to electron configurations—particularly of ions—and to periodic properties. Challenges for teaching this material include:
Pre-existing misconceptions (orbits versus orbitals)
Non-intuitive aspects of quantum mechanics (wave nature of particles, quantized energy)
The concept of quantum numbers which may have no precedent for students
An image representing a probability (orbital) rather than a definitive physical entity
A careful study of the figures should help in their understanding of these ideas. Students should be urged to master both the new concepts and the mathematical relationships among them. It may be hard for them to appreciate the significance of the quantum model, but they will soon see consequences of this world in periodic properties, bonding, polarity and later in spectroscopy. New to this edition is the incorporation of a section on electron spin and magnetism into this chapter, material that previously was included in the chapter on electron configurations and periodic trends. We have included resources for demonstrating the paramagnetism of liquid oxygen below, and the demonstration can be repeated when covering molecular orbital theory in Chapter 9. Students have experience with magnetism so the inclusion of this topic in the chapter should provide them with something familiar to relate to the new information which they are learning. Continuing the study of magnetism through the application of the well-known MRI technique should provide some
