Quick Answer:The Diamond Crystal Model is a 3D model of the diamond lattice in which every carbon atom is bonded to four others in a tetrahedral arrangement, explaining diamond’s hardness and thermal conductivity.

How It Is Used
Students build tetrahedral units from the carbon spheres and connectors and extend them into a 3D lattice. The model is then used to explain strong covalent bonding throughout the crystal and why diamond is so hard, and to contrast it with the layered structure of graphite.
