*** WHAT'S COVERED ***
1. Allotropes of Carbon
* Definition of allotropes as different structural forms of the same element.
* Introduction to diamond, graphite, graphene, and fullerenes.
2. Structure and Properties of Diamond
* A giant covalent structure.
* Each carbon atom is covalently bonded to four other carbon atoms.
* Forms a regular, rigid 3D lattice.
* Properties: very strong, high melting point, and does not conduct electricity as there are no free electrons.
3. Structure and Properties of Graphite
* A giant covalent structure arranged in layers.
* Each carbon atom is bonded to three other atoms, forming hexagonal rings.
* Layers are held by weak forces and can slide over each other, making graphite soft.
* Has a high melting point due to strong covalent bonds within the layers.
* Conducts electricity and heat due to delocalised electrons between the layers.
4. Graphene and Fullerenes
* A brief introduction to graphene as a single layer of graphite.
* A brief mention of fullerenes.
