Diamond and Graphite
- Graphite
- Layered Structure
- Weak intermolecular forces between the layers
- the layers can slide over each other making graphite slippery
- Graphite in pencils leave
the black mark as it wears
away
- Good
lubricants as it
also has a high
melting point
so won't break
down like oil
would

- the layers can slide over each other making graphite slippery
- Weak intermolecular forces between the layers
- Each carbon atom is
joined to 3 other
atoms with strong
covalent bonds
- One free delocalised electron
- Can be used as electrodes as it can conduct electricity
- It can conduct heat

- Diamond
- Hard
- Cutting tools
- Cutting tools
- Lustrous and transparent
- can be cut into shapes to allow light to pass through
it to make it look like its sparkling
- jewellery

- can be cut into shapes to allow light to pass through
it to make it look like its sparkling
- Each carbon atom forms strong
covalent bonds with 4 other
atoms to form a giant covalent
structure
- Explains its
extreme
hardness and
high melting
point
- Cannot conduct
electricity as there are
no delocalised electrons
who are free to move to
carry charge

hardness and
high melting
point
