Ionic compounds usually contain a metal (from the left side of the periodic table) and a nonmetal (from the right side of the periodic table, other than the noble gases). Some ionic compounds contain polyatomic ions, such as the sulfate ion SO42–. Ternary compounds technically contain three elements; however, more may be present. The names of ionic compounds consist of two or more words. The last word in the name of a binary compound has an -ide suffix. The last word in the name of a ternary compound usually has an -ite or an -ate suffix. Pure acids are generally not ionic, but they produce ions in solution.
The Problems You’ll Work On
In this chapter, you work with ionic bonding in the following ways:
Naming binary compounds
Naming ternary compounds
Writing formulas for ionic compounds
Note: See the Appendix if you need to check the periodic table.
What to Watch Out For
Remember the following when working on ionic bonding problems:
The names of inorganic compounds normally consist of two words.
All simple binary compounds have an -ide suffix on the second ...
