Metallic Bonding

• Metals join together through Metallic Bonding
• The bonding in a metal consists of positive ions electron and delocalised electrons arranged in a regular pattern.
• The delocalised electron system in metallic bonding consists of the electrons ‘lost’ from the atoms to form positive ions.
• Metallic Bonding

  • Delocalised electrons are free to move through the structure.
  • The delocalised electrons are shared through the structure so metallic bonds are strong.
• Metals are good conductors of heat & electricity due to the delocalised electrons
• Metallic Bonding

  The positive ions and delocalised electrons create strong electrostatic attraction which holds everything together
• Metals are malleable as their layers can slide over one another easily when pressure is applied. This allows metals to be hammered into different shapes without breaking apart.
• Metal structures have high melting points because they require a lot of energy to break the strong metallic bonds between the positive ions and delocalised electrons.
• Metals are ductile as they can be drawn out into thin wires or sheets without breaking apart. The delocalised electrons allow the layers of positive ions to slide past each other allowing them to stretch out into long thin wires.
• Metals have high melting points because they require energy to break the strong metallic bonds between the positive ions and delocalised electrons.
