5.2.2.3 AQA Properties of Ionic Compounds Quiz

What type of structures do ionic compounds have?

• Amorphous structures

• Giant ionic lattices

• Molecular structures

• Covalent networks

What causes the strong electrostatic forces of attraction in ionic compounds?

• Attraction between neutral atoms

• Attraction between oppositely charged ions

• Attraction between molecules

• Attraction between electrons and neutrons

Why do ionic compounds have high melting and boiling points?

• Because of weak bonds

• Because of large amounts of energy needed to break the strong bonds

• Because of low energy requirements

• Because of their molecular structure

What happens to ionic compounds when they are melted or dissolved in water?

• They become non-conductive

• They conduct electricity

• They form covalent bonds

• They evaporate

Why can ionic compounds conduct electricity when melted or dissolved in water?

• Because the ions are free to move and so charge can flow

• Because the molecules are free to move

• Because the atoms are free to move

• Because the electrons are free to move

Is knowledge of the structures of specific ionic compounds other than sodium chloride required?

• Yes, it is required

• No, it is not required

• Only for some compounds

• Only for advanced studies

What is NOT a characteristic of ionic compounds?

• High melting points

• High boiling points

• Weak electrostatic forces

• Conductivity when dissolved in water

What type of bonds are present in ionic compounds?

• Covalent bonds

• Metallic bonds

• Hydrogen bonds

• Strong electrostatic bonds

What is the primary reason for the high boiling points of ionic compounds?

• Low energy needed to break bonds

• High energy needed to break bonds

• Presence of covalent bonds

• Presence of metallic bonds

What is the state of ions in ionic compounds when they conduct electricity?

• Fixed in place

• Free to move

• Bound to molecules

• In a gaseous state
