Unit 2 · Compound Structure and Properties

Chapter 2.1

Types of Bonds and the Energy of Holding Atoms Together

Salt shatters, wax bends, copper conducts, and all three are just atoms holding hands in different ways. Pull two atoms apart on an energy graph and the bond's length and strength both appear.
