Whether diamond or graphite shows the greater density needs to be determined. Concept introduction: In diamond, it has a tetrahedral arrangement of carbon atoms. Each carbon atom is attached to four other carbon atoms via covalent bonds with 1.544 × 10 − 10 meter distance and with 109.5 0 bond angle. It is a strong and rigid 3D structure that results in an infinite network of atoms. Graphite is also arranged in an infinite array, but it has a layered structure. Each carbon atom is bonded to three other carbon atoms and arranged at the corners of a network of regular hexagons with a 120 0 bond angle. These planar arrays are held together by stacking interactions which are weaker forces. The distance between two layers is 3.347 × 10 − 10 meter and distance between carbon atoms within each layer is 1.418 × 10 − 10 meter. This 3D structure is related for the physical properties of graphite.
