Diamond, graphite and graphene are forms of carbon ... Sample exam questions - bonding, structure and matter - AQA Understanding how to approach exam questions helps to boost exam performance.

Carbon atoms can form four covalent bonds. This is why they can form many different organic substances, such as diamond, graphite and fullerenes.

and this is exactly what these carbon bonds do in graphite. These triangular structures join up with one another to form flat sheets of hexagons. The weakness comes from the very weak forces of ...

Thanks to the crystal structure of diamonds ... we synthesized HD from graphite via intermediate post-graphite phases in which interlayer bonding may lock a near-AB stacking in the compressed ...

The archetypal example is C 60 fullerene, where the atoms and bonds delineate ... These same structures are also known as Buckyballs or fullerenes. Buckminsterfullerene is the third allotrope of ...
