Learning Plan

  1. Watch the video on naming ionic compounds with polyatomic ions.

  2. Review Essential Information on naming ionic compounds with polyatomic ions.

  3. Correctly name ten in a row!


Once you get ten in a row, return to the Syllabus or continue to the next section (Formula Writing for Ionic Compounds with Polyatomic Ions).

Essential Information

Keys for Naming Ternary Ionic Compounds
  • Name the metal (the cation) as it appears on the Periodic Table.
    • Na+ = Sodium    Al3+ = Aluminum
  • Find the polyatomic ion on the Common Ion Table and write the name.
  • Note: It is possible to have two polyatomic ions such as NH4NO3. In this case find and write both names as found on the Common Ion Table.
