Metallic Bonding

• Metallic bonds are the electrostatic forces of attraction between metal ions and the delocalised electrons in a metallic lattice.
• Metallic Bond Strength: This is dependent on the charge of ions in a lattice and the number of electrons in the sea of delocalised electrons.
• Properties of metals:

  • Good conductors of heat and electricity. This is because the electrons are free to move throughout the structure and carry a charge.
• Properties of metals:

  • High MP and BP. The electrostatic forces of attraction between the ions and the electrons are very large which means that they require a lot of energy to break, increasing the MP and BP.
• Properties of metals:

  • Metals are malleable and ductile. The layers of ions can slip over each other. This means that they can be bent and reshaped as needed.
