True or false? Ionic compounds have high melting points because the forces of electrostatic attraction holding them together are strong.

True or false? Solid ionic compounds conduct electricity because the ions are locked tight together and can pass on charge.

True or false? Simple covalent molecules conduct electricity when liquid.

True or false? We create alloys to reduce the malleability of metals by breaking up the layered structure of the metal.

True or false? The sea of delocalised electrons in metals prevents them from conducting electricity.

True or false? Modern sunscreens use titanium oxide nanoparticles because they are more effective than conventional UV ray blockers.

True or false? Nanoparticles are ineffective catalysts due to their small size.
