Final answer:
Ammonium nitrate is the name of the ionic compound NH4NO3, composed of the ammonium ion (NH4+) and the nitrate ion (NO3-).
Step-by-step explanation:
The ionic compound NH4NO3 is named ammonium nitrate. This compound is composed of the ammonium ion (NH4+) and the nitrate ion (NO3-). Naming ionic compounds that contain polyatomic ions like these involves using the names of the ions as they are. No prefixes are needed and the name of the cation comes first, followed by the name of the anion. Ammonium nitrate contains both ionic and covalent bonds as the ammonium and nitrate ions are held together through ionic bonds while within the nitrate ion, the nitrogen and oxygen atoms are connected by covalent bonds.
