1,001 Chemistry Practice Problems For Dummies (2014)

Part I. The Questions

Chapter 6. Ionic Bonding

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 -idesuffix. 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:

check Naming binary compounds

check Naming ternary compounds

check 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:

check The names of inorganic compounds normally consist of two words.

check All simple binary compounds have an -ide suffix on the second word in the name.

check The -ide suffix is not common in compounds containing three or more elements. Most compounds containing three or more elements have either an -ite or -ate suffix.

check Don’t use multiplying prefixes, such as di- and tri-, for ionic compounds.

check If you use the “crisscross” rule, don’t forget to reduce.

check Acids follow their own rules for naming.
