in diamond how many carbon atoms is each carbon attached to?
4
in graphite how many carbon atoms is each carbon attached to?
3
what shape rings do graphite layers form?
hexagonal
is graphite soft or hard? why?
soft. no covalent bonds between the layers = layers slide over each other easily.
can diamond conduct electricity? why?
no. there are no delocalised electrons to carry charge.
can graphite conduct electricity? why?
yes. one carbon atom from each electron is delocalised meaning it can carry charge.
graphene is a single layer of what?
graphite
graphene is very strong and elastic. why?
strong because of very tightly bonded layers, elastic because planes of atoms can flex relatively easily without atoms breaking apart.
what are fullerenes?
molecules of carbon with hollow shapes
how many carbon atoms does a buckminsterfullerene have?
60
carbon nanotubes have a high what to what ratio?
surface area to volume
what can nanotubes be used for?
lubricants, drug delivery and catalysts.
