Ions that are made up of more than one atom are called what?

• A. Ion
• B. Valence electrons
• C. Electron dot diagram
• D. Polyatomic ions

Answer: (D)

Polyatomic ions are ions that consist of two or more atoms bonded together and carry a net charge. This makes them different from a simple ion, which is a single atom that has gained or lost electrons. A polyatomic ion is treated as a single unit in compounds, with a fixed overall charge, like sulfate (SO4^2−) or ammonium (NH4^+). Valence electrons are the outer-shell electrons, not ions themselves, and an electron dot diagram is a way to represent those electrons. Therefore, an ion made up of more than one atom is called a polyatomic ion.
