level questions: Graphene and fullerenes
| Question | Answer |
|---|---|
| What is graphene | A single layer of graphite |
| How thick is graphene | One atom thick even though its light, its strong because of the covalent bonds |
| Why is graphene a good conducter of electricity | Because it has delocalised electrons just like graphite |
| What are fullerenes | Molecules of carbon with hollow shape |
| What is the usal shape of fullerenes | hexagonal but they can have rings with 5or 7 carbon atoms |
| What was the first fullerene | Buckministerfullerene C60 |
| What are the use of spherical fullerene | - medicine - lubricants - catalyst |
| Give me another group of fullerenes | Carbon nanotubes (shape is a long cylinder) |
| Give me some properties of carbon nanotubes | High tensile strength good conducters of heat and electricity |
| Give me a use of carbon nanotubes | reinforce materials e.g. tennis racket |
