Introduction
In this chapter, we first looked at the naming conventions for ionic compounds, which exist as extended networks of
cations and anions. For most of the compounds that we considered, the cation was a monatomic metal (e.g., Na+,
Mg^2 +, Fe^3 +), and the anion was a monatomic nonmetal (e.g., Cl−, O^2 −, N^3 −) or a polyatomic ion, which often
contains multiple oxygen atoms (e.g., SO 42 −). We then looked at molecular compounds, in which atoms are held
together into individual molecules by covalent bonds. Now we are going to consider acids and bases, which share
characteristics with both ionic and molecular compounds.
