Key Features
Carbon atoms arranged in hexagonal layers.
Strong bonding within each layer and weak connections between layers.
Plastic atom spheres and connecting rods on a base stand.
Assembled by the user into a layered hexagonal lattice.

How It Is Used
Students join the carbon spheres into hexagonal rings, build these into flat layers and stack the layers on the stand. The finished model is used to explain covalent bonding within the layers, the weak forces between them, and how this structure gives graphite its softness and conductivity; comparing it with a diamond model highlights the difference between the two carbon allotropes.
