Pure Metals
Pure metals have giant structures with strong electrostatic forces between positive ions and delocalised electrons. All of the ions are the same size and these ions are arranged in layers. Pure metals have the following properties:
High melting and boiling points
- There are strong electrostatic forces between the positive metal ions and the negative delocalised electrons.
- This means that metals have high melting and boiling points.
Soft and malleable
- Because the ions are arranged in layers, they easily move over each other when a force is applied.
- This means that pure metals are soft and malleable.
