Diamond, Graphite and Fullerenes are allotropes
of Carbon.

Allotropes are different forms of the same element
with atoms arranged in different molecular
structures.

Diamond is made of carbon atoms bonded to four other carbon atoms
by strong covalent bonds
Diamonds have a rigid structure.

They are insoluble in water because it has weak bonds.

They don't conduct electricity because it has no free
electrons.
They can be used to cut tools because…

Graphite has a layered structure
It's insoluble in water because it has weak intermolecular
bonds.
Conducts electricity because it has delocalised
electrons.
It has a high melting point because it has many strong
covalent bonds to break

A Buckminster fullerene consists of 60
Carbon atoms arranged into a sphere
It's symbol is C60

It's a black solid

It makes a red solution when dissolved in petrol.

Chemists discovered that nanotubes could be made by joining
fullerenes together.

They conduct electricity and are very strong
They are used to reinforce graphite tennis rackets
because of their strength.
They are used to make connectors and semiconductor
in the most modern molecular computers because of
their electrical properties…
