nanochemistry
- Diamond and graphite properties
- Graphite
- Insoluble in water
- Very high melting point
- Lower than diamond
- Has weak bonds
- Conducts electricity
- Soft & Slippery
- Lustrous
- Opaque &
Black
- Diamond
- Transparent
- Very hard
- Very high
melting point
- Doesn't conduct
electricity
- Insoluble in water
- Lustrous (Shiny)
- Colourless
- Structure
- Diamond
- All 4 electrons in a strong covalent bond
- Graphite
- weak intermolecular forces
- Strong covalent bonds
- Hexagonol rings
- Only 3 electrons in bond
- The fourth electron is free (delocalized)
- Soft layers - easily broken
- Buckminsterfullerene
- Hexagonol & Pentagonal rings
- Conducts electricity
- Allotrope
- Same element but different
arrangement of atoms
