Graphite atomic spacing
Did you know?
Graphite is a crystalline form of the element carbon. It consists of stacked layers of graphene. Graphite occurs naturally and is the most stable form of carbon under standard conditions. Synthetic and natural graphite are consumed on large scale (300 kton/year, in 1989) for uses in pencils, lubricants, and electrodes. Under high pressures and temperatures it converts to diamond. It is a good (b… Web(Bottom) Graphite crystal structure, depicting an atomic spacing of 0.142 nm. Atomic spacing refers to the distance between the nuclei of atoms in a material. This space is extremely large compared to the size of the …

Thus the smallest ring is a result of reflections off a family of planes which all have the same interplanar spacing, and being the smallest ring, these planes must be the ones with the biggest interplanar spacing.

Bond length can be determined between different elements in molecules by using the atomic radii of the atoms. Carbon bonds with itself to form two covalent network solids. Diamond's C-C bond has a distance of Sqrt[3]a/4 ≈ 0.154 nm away from each carbon since adiamond ≈ 0.357 nm, while graphite's C-C bond has a distance of a/Sqrt[3] ≈ 0.142 nm away from each carbon since agraphite ≈ 0.246 nm.
