giant covalent structures

?
what are two forms os carbon?
diamond and graphite
1 of 11
describe the properties of diamond
3D structure; covalently bonded to four other carbons; hard;transparent
2 of 11
what compund has a similar structure?
silicon dioxide
3 of 11
describe the properties of graphite
atoms covalently bonded to three other carbon atoms; 2D layers; no covalent bonds between layers
4 of 11
how is graphite slippery and grey
weak intermolecular forces between layers make them slide over eachother
5 of 11
in graphite atoms form a flat sheet of...
hexagons
6 of 11
how is graphite like a metal?
one electron from each carbon atom is delocalised, allowing graphite to conduct electricty
7 of 11
what are fullerenes?
large molecules formed from hexagonal rings of carbon atoms.
8 of 11
what size are some of the shapes?
nano-sized
9 of 11
what applications do fullerenes have?
drug delivery into body;lubricants; catalysts
10 of 11
what do graphite and diamond both have and why?
high melting and boiling points, giant covalent structure
