allotropes of carbon

Cards (8)

what is diamond made up of?
a carbon atom forms four covalent bonds
what is diamonds properties?
very hard
high melting point -> takes a lot of energy to break covalent bonds
doesn't conduct electricity -> no free electrons
what does graphite form?
a carbon atom forms 3 covalent bonds, forming layers of hexagons
what are the properties of graphite?
soft and slippery -> no covalent bonds between layers so are free to move over eachother
high melting point
conducts electricity -> each carbon atom has one delocalised electron
what are the allotropes of carbon?
diamond, graphite, silicon dioxide and fullerenes
what was the first fullerene discovered?
the buckminsterfullerene
shaped in a hollow sphere in hexagons
what are the uses of fullerenes?
delivering drugs, catalysts and lubricants
What do nanotubes do? 
they are tiny carbon cylinders
used in electronics or to strengthen materials without adding much weight. This is called nanotechnology
