1.45 explain how the uses of diamond and graphite depend on their structures, limited to graphite as a lubricant and diamond in cutting.

THE USES:

- Diamond can be used for cutting since each carbon atom forms four covalent bonds in a giant covalent structure; this means that it is very hard and is the hardest natural substance.

- Graphite is great for a lubricant since each carbon atom only forms three covalent bonds. This means that there are layers, which are free to slide over each other.
