Final answer:
Ionic compounds with polyatomic ions are named by combining the cation and anion names. Charges are not included in the name, but the formula shows how the charges balance. For example, NaNO3 is sodium nitrate.
Step-by-step explanation:
When naming ionic compounds that contain polyatomic ions, you follow the same naming rules as for other ionic compounds. The name of the cation is combined with the name of the anion. Charges are not included in the name, as the formula shows how the positive and negative charges balance. For example, NaNO3 is named sodium nitrate and CaCO3 is calcium carbonate.
