Conductors and Insulators

What is a conductor

A material which allows the flow of electric current to pass through it

What material is a good conductor and why

Metals are good conductors because they have delocalised electrons

What are insulators

Materials which do not allow the flow of electric current to pass through them

What material is a good insulator

Plastics are good insulators because they do not have delocalised electrons

Can ionic compounds conduct electricity

Ionic compounds can conduct electricity in solutions because their ions are free to move
