Metallic Bonding

• Describe the metallic structure

  • Atoms form layers
  • Delocalised electrons on outer shell
  • Positive metal ions are attracted to delocalised electrons by electrostatic force of attraction
• What are the metallic properties?

  • Malleable (layers can slide)
  • Can conduct electricity (delocalised electrons)
  • Can conduct thermal energy (delocalised electrons)
  • High melting point(strong electrostatic attraction)
  • High boiling point (strong electrostatic attraction)
• What is an alloy?

  • Metals are too soft
  • They are mixed with a different element to harden
  • Layers cannot slide
