How to answer a "Describe the structure and bonding in..." question.
How to use this diagram:
1) Look at what sort of bonding your question is asking you about - is it ionic, covalent or metallic?
2) Once you know, follow that path and read all of the points. You can then mention them in your answer.

- Describe the structure and bonding in...
- Is it metallic?
- Giant Metallic
- It has layers.
- It contains positive ions.
- It contains delocalised electrons.
- There is an electrostatic force of attraction between the DE's and the PI's.
- It contains positive ions.
- It can conduct electricity (a property)
- There is an electrostatic force of attraction between the DE's and the PI's.
- E.G: Iron (Fe)
- Giant Metallic
- Is it ionic?
- Giant Ionic
- Electrostatic forces of attraction between + and - ions.
- In all directions.
- Electrostatic forces of attraction between + and - ions.
- E.G: Sodium Chloride (NaCl)
- Giant Ionic
- Is it covalent?
- Is it a Giant Covalent?
- E.G: Diamond / Graphite / Silicon Dioxide
- Diamond and Graphite are made of Carbon.
- Graphite
- 3 Bonds
- 1 Delocalised Electron
- It conducts electricity (a property)
- 1 Delocalised Electron
- 3 Bonds
- Diamond
- 4 Bonds
- This is why it is hard (a property)
- 4 Bonds
- Graphite
- Is it a Simple Molecule?
- It has weak intermolecular forces.
- You could mention the properties too, if required.
- E.G: Water (H2O)
- It has weak intermolecular forces.
- Is it a Giant Covalent?
- Is it metallic?
