Naming Ionic Compounds
Professor Dave Explains
Guided Notes
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.
