A compound that consists of positive and negative ions is called what?

• A. Molecular compound
• B. Element
• C. Ionic compound
• D. Mixture

Answer: (C)

This question tests your understanding of ionic bonding. When a substance is made up of positive and negative ions held together by strong electrostatic forces, it forms an ionic compound. These ions come from transferring electrons from a metal to a non-metal, creating oppositely charged particles that attract each other in a lattice. That structure gives ionic compounds characteristic properties like a high melting point and the ability to conduct electricity when melted or dissolved.

A molecular compound, in contrast, is held together by covalent bonds between neutral atoms. An element is a pure substance consisting of only one type of atom, not bonded ions. A mixture is a combination of substances that are not chemically bonded to each other. Therefore, a compound that consists of positive and negative ions is an ionic compound.
