High melting point/Hard as strong covalent bonds hold the structure/Doesn’t conduct electricity/Used for diamond tipped glass cutters and oil rig drills
Graphite
3 Carbon to Carbon Bonds
Forms layer of hexagonal rings
No covalent bonds between layers
One delocalised electron
Graphite
Conducts electricity
Weak intermolecular Forces between layers are weak so they slide over one another so they are soft/slippery
Used as lubricant
Silica(Silicone Dioxide)
Silicon and oxygen atoms
Strong covalent bonds in regular arrangement
Silica(Silicone Dioxide)
High melting and boiling point
Doesn’t conduct electricity
Fullerenes
Hollow shapes based on hexagonal rings joined by covalent bonds
Fullerenes
Buckiminster fullerene (spherical):weak intermolecular forces so low melting point and slippery
Graphene
Single layer of graphite
Strong covalent bonds
Strong
Delocalised electron
Graphene
Conducts electricity
High melting point
Used for making composites and in electronics
Graphene
Layer of Graphene is called a nanotube.High length to diameter ratio,conduct electricity and have high tensile strength(strong in tension)Used for nanotechnology,electronics
