Ionic Compound Names and Formulas
Learning Objective
I can name ionic compounds, including those with polyatomic ions and transition metals with multiple oxidation states, and write their formulas from their names.
Key Concepts
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.
