What is X?

Ionic compounds conduct electricity when dissolved in water. Which statement below best explains the property?

• Ions are free to move.

• Electrons are free to move.

• Bonds are strong.

• There are weak intermolecular forces of attraction.

Properties of ionic compounds include:

• brittle, conducts electricity (aqueous state), high melting points

• usually gas or liquid, relatively low melting points, does not conduct electricity

• shiny, malleable, ductile, conducts electricity, usually a solid
