Graphene and fullerenes Flashcards
1
Q
What is graphene?
A
A single layer of graphite with useful properties in electronics and composites.
2
Q
What are fullerenes?
A
Molecules of carbon atoms with hollow shapes, based on hexagonal rings but may include rings with five or seven carbon atoms.
3
Q
Give an example of a fullerene and its shape.
A
Buckminsterfullerene (C60), which has a spherical shape.
4
Q
What are carbon nanotubes?
A
Cylindrical fullerenes with very high length-to-diameter ratios, useful for nanotechnology, electronics, and materials.
5
Q
What skills should students develop regarding graphene, fullerenes, and carbon nanotubes?
A
Recognizing them from diagrams and descriptions of bonding and structure, and giving examples of the uses of fullerenes, including carbon nanotubes.
