Graphite
General properties :-
Structure of Graphite :-
A graphite crystal consists of layers of carbon atoms or sheets of carbon atoms. Each carbon atom in a graphite layer is joined to three other carbon atoms by strong covalent bonds to form flat hexagonal rings. However, the fourth electron of each carbon atom is free which makes it good conductor of electricity. The various layers of carbon atoms in graphite are held together weak Van Der Waals’ forces so these can slide over one another and therefore, graphite is slippery to touch.
Uses of Graphite :-
• It is used as a powdered lubricant for the parts of machinery.
• It is used for making electrodes of cells and lead for pencils as it can mark paper black. It is therefore called black led or plumbago.
