Topic Summary: Metallic Bonding
Key Terms
- Metallic bond: attraction between positive metal ions and delocalised electrons
- Delocalised electrons: free electrons not fixed to any atom
- Sea of electrons: the mobile electron cloud in a metal
- Malleable: can be hammered into shape
- Ductile: can be drawn into wire
Must-Know Facts
- Positive metal ions surrounded by sea of delocalised electrons
- Conducts electricity — delocalised electrons carry charge
- Conducts heat — electrons transfer kinetic energy
- Malleable/ductile — layers slide, electrons maintain bond
- High MP — strong attraction between ions and electrons
- Conducts as a SOLID (unlike ionic compounds)
