What properties does an ionic compound have?

• A low boiling point and it conducts electricity when dissolved in water

• A high melting and it conducts electricity when liquid

• A high boiling point and it conducts electricity when solid

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.

The reason that a sodium atom bonds with a chlorine atom is because

• Sodium transfers an electron to Chlorine
• oppositely charged ions form a strong electrostatic attraction
• ions are the same size
• the ions have a full outer shell
