Edexcel IAL Chemistry AS 3.20 Metallic lattice model
Edexcel IAL Chemistry AS 3.20 Metallic lattice model
Identify the metal's ion charge, arrange cations in a regular lattice and place mobile electrons between them before labelling the electrostatic model.
How this is tested
- Draw a labelled metallic lattice with positive metal ions and delocalised electrons.
- Identify a metal as a giant metallic structure rather than an ionic or molecular solid.
