Naming Ionic Compounds

Professor Dave Explains

Guided Notes

16 min

Key concepts students will learn:

  • In naming ionic compounds, the cation is always listed first, followed by the anion, and monatomic anions typically end with the suffix -ide.

  • When naming ionic compounds with transition metals that have multiple oxidation states, use Roman numerals in parentheses to indicate the charge of the metal cation, such as iron(II) or copper(I).

  • For polyatomic ions with varying numbers of oxygen atoms, the ion with more oxygen atoms uses the suffix -ate, while the ion with fewer oxygen atoms uses the suffix -ite.
