- Giant Covalent Structures
- Diamond
- Form of carbon
- Regular 3D, giant structure
- Each C atom is covalently bonded to 4 other atoms
- This makes it hard and clear
- Graphite
- Another form of carbon
- Each atom if covalently bonded to 3 other atoms
- Structured into flat 2D layers
- Layers slide over each other, cause no covalent bonds between each layer
- Can conduct electricity due to delocalised electrons (from the carbon atoms)
- Fullerenes
- Large molecules formed from hexagonal rings of carbon atoms
- Rings join together to make cage-like structures, with different numbers of C atoms (some nano-sized)
- Used for drug delivery into body, lubricants, catalysts, and reinforcing materials
- Diamond
