Study Notes
Ionic Compounds
- Composed of a metal and a nonmetal.
- The metal forms a positively charged ion (cation).
- The nonmetal forms a negatively charged ion (anion).
- Some metals form only one type of ion, while others can form multiple types with different charges.
Molecular Compounds
- Composed of only nonmetals.
Acids
- Contain hydrogen (H) and one or more nonmetals.
- Binary acids are composed of two elements.
- Oxyacids contain oxygen.
-
Naming Acids:
- If the oxyanion ends in -ate, the acid name ends in -ic.
- If the oxyanion ends in -ite, the acid name ends in -ous.
Naming Conventions
-
Cations:
- The name of the cation (metal) is used.
- The charge of the cation (metal) is indicated by a Roman numeral in parentheses.
-
Anions:
- The base name of the anion (nonmetal) is used, followed by the suffix -ide.
-
Two-element compounds:
- A prefix indicates the number of atoms of the first element.
- The base name of the second element is used, followed by -ide.
-
Acids:
- For binary acids, the prefix hydro is used, followed by the nonmetal name with the suffix -ic.
- For oxyacids, the nonmetal name is used with the suffix -ic or -ous, depending on the oxyanion ending.
Additional Notes
- Acids must be in an aqueous solution.
