Unit 13: Modern Materials and the Solid State—Crystals, Polymers, and Alloys


Unit Overview

Understanding the inter-atomic forces that give structure and properties to different types of solids is essential for the creation of new alloys, the development of useful polymers, and the creation of many other kinds of man-made materials. In this closing chapter, we see chemistry not only as an excellent entry point to predicting how a new material behaves, but also as a continuous process of innovation and discovery.
