A L L O T R O P E S : PART 1
- Carbon atoms can form four covalent bonds. This lets it form many different organic substances, and exist as diamond, graphite and fullerenes.
F U L L E R E N E S
N A N O T U B E S
- A nanotube resembles a layer of graphene, rolled into a tube shape.
- Nanotubes have high tensile strength, so they are strong in tension and resist being stretched and have a huge surface area.
- Nanotubes. are strong and they conduct electricity because they have delocalised electrons.
B U C K Y B A L L S
- Buckyballs are spheres or squashed spheres of carbon atoms and they are made of large molecules but do not have a giant covalent structure.
- They have a weak intermolecular force that exists between individual buckyballs. which makes them have little forces to overcome forces
- They are slippery and have low melting points than graphite or diamond.
- They are used to trap and deliver drugs in the body, made for tennis rackets and acts as a catalyst.

ALLOTROPES: Part 2
D I A M O N D S
- Are insoluble in water as they do not conduct electricity as there are no delocalised electrons in it's. structure
- They have a high melting point and are very hard.
- They are colourless and transparent
- They have no free electrons but they. have 4 strong covalent. bonds.
- They are used for cutting tools, making jewellery, drill bits, glass cutters and dental drills
- They have a lustrous appearance to make them look highly valued gemstones for jewellery.
G R A P H I T E
- Graphite has 3 carbon atoms and has strong covalent bonds and free electron layer that slide over.
- Graphite is useful for leads and electrodes.
- Graphite has a black, opaque(unclear), lustrous look.
- Graphite is soft and slippery. They are insoluble but it has a high boiling point and is made of hexagonal rings.
- Graphite conducts to electricity and is used in lubricants that work at a heating temperature
