40 • Chapter 2 / Atomic Structure and Interatomic Bonding<br />

Processing/Structure/Properties/Performance Summary<br />

In this chapter, we noted that the electron configuration of an atom influences the<br />

type of bonds that it forms with other atoms. Bonding type also affects other structural<br />

elements of the material: for silicon, its electron band structure (Chapter 18);<br />

for polymeric materials (i.e., fibers), their molecular structures (Chapter 14). These<br />

relationships are represented in the following diagrams.<br />

Note: In each chapter, most of the terms listed in the Important Terms and Concepts section<br />

are defined in the Glossary, which follows Appendix E. The others are important<br />

enough to warrant treatment in a full section of the text and can be referenced from the<br />

Table of Contents or the Index.
