When polyatomic ions bond with other ions, what type of compound is typically formed?

• A. Elemental molecule
• B. Ionic compound
• C. Covalent compound
• D. Metallic compound

Answer: (B)

Verified step by step guidance

1. Understand that polyatomic ions are groups of atoms covalently bonded together that carry an overall charge.
2. Recognize that when polyatomic ions bond with ions of opposite charge, the attraction between these charged species leads to the formation of an ionic bond.
3. Recall that ionic bonds form between positively charged ions (cations) and negatively charged ions (anions), resulting in an ionic compound.
4. Note that although the atoms within the polyatomic ion are held together covalently, the bond between the polyatomic ion and another ion is ionic in nature.
5. Therefore, when polyatomic ions bond with other ions, the compound formed is typically an ionic compound.
