This chapter discusses how chemical bonds result from the sharing or transfer of valence electrons between pairs of atoms. The formation of an ionic bond between an anion and a cation is described. Properties of ionic compounds, such as high melting points, are attributed to the properties of their ionic bonds. The properties of metallic bonds are described and compared to properties of ionic bonds.

In this chapter, you will learn: to use the periodic table to infer the number of valence electrons to characterize an ionic bond to explain the electrical conductivity of ionic compounds to use the theory of metallic bonds to explain physical properties of metals to describe the arrangements of atoms in common metallic crystal structures
