Key Stage 4
Meaning
Graphene is an allotrope of carbon in which the atoms are bonded in a hexagonal arrangement in a single layer.
A diagram showing the arrangement of carbon atoms in graphene. |
About Graphene
- Graphene is a giant covalent structure.
- Graphene is a single layer of graphite.
- Graphene is a good electrical conductor because it only uses 3 out of the 4 electrons in the outer shell to bond with other atoms allowing the last electron to move freely around the giant covalent structure.
- Large sheets of graphene are extremely strong which is a very useful property. A layer of graphene as thin as cling film could support the weight of an entire elephant.
