Key concepts
3 concepts
- 1
In naming ionic compounds, the cation is always listed first, followed by the anion, and monatomic anions typically end with the suffix -ide.
- 2
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).
- 3
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.
