Which statement is true about ionic compounds?

A. They are made up of many large molecules that are bonded together.
B. They are made up of atoms of only one type of element.
C. They are made up of particles that are arranged in a repeating pattern.
D. They are made up of a random ratio of elements that are bonded together.



Answer :

Final answer:

Ionic compounds consist of ions held together by ionic bonds, exhibit unique properties, and have varied conductivity.


Explanation:

Ionic compounds are composed of ions held together by ionic bonds, which are electrostatic forces between oppositely charged cations and anions. These compounds exhibit a crystalline structure, have high melting and boiling points, and are poor conductors of electricity in their solid state. However, when dissolved or melted, they become excellent conductors of electricity and heat.
