WebApr 5, 2024 · The difference between Diamond and Graphite is that Diamond has a crystalline lattice, where the atoms of carbon are arranged in a three-dimensional symmetry within the crystal. Meanwhile, graphite has a layered structure, where rings of six carbon atoms are arranged in a spaced horizontal sheet. WebJul 7, 2024 · The crystal structure of a diamond is a face-centered cubic or FCC lattice. Each carbon atom joins four other carbon atoms in regular tetrahedrons (triangular prisms). Based on the cubic form and its highly …
WebThe crystal structure of diamond is an infinite three-dimensional array of carbon atoms, each of which forms a structure in which each of the bonds makes equal angles with its neighbours. If the ends of the bonds are connected, the structure is that of a tetrahedron, a three-sided pyramid of four faces (including the base).
