(h) Metallic Bonding

• Metallic bonding is formed from the electrostatic forces of attraction between positive metal ions and a sea of negative, delocalised electrons
• Metals are good conductors of electricity because it contains free electrons that are able to travel through the structure and carry a charge
• There are strong electrostatic forces of attraction between the positive metal ions and a sea of delocalised electrons so lots of energy is needed to overcome this, hence metals have high boiling points
• In pure metals, all the ions are arranged into layers and they are the same size so if a force is applied to the lattice, the layers can slide over one another. This is why they are malleable and ductile
