Metals are made up of positive metal ions which are arranged closely together within a sea of delocalised electrons. We can use this model to explain the properties of metals.

In this topic you need to know about the following: -

  • How we can use the model to explain why metals conduct electricity.
  • How we can use the model to explain why metals are malleable (can bend).
  • How we can use the model to explain why metals have high melting points.
