A
4
2
Q
What structure does diamond have
A
Giant covalent structure
3
Q
What structure does graphene have
A
Giant covalent structure
4
Q
What structure does fullerene have
A
Molecular structure
5
Q
How many carbon atoms joins to each carbon atom in fullerene and graphene
A
3
6
Q
Why do Diamond and graphene have high melting points
A
Many bonds need to be broken to melt so needs lots of energy
7
Q
Can diamond conduct electricity
A
No, because it has no free moving electrons
8
Q
Can fullerene and graphene conduct electicity
A
yes because they have one free electron per carbon atom
9
Q
How well does fullerene conduct electricity
A
No well due to electricity across the surface of the molecule
