The same atoms arranged into a tetrahedral lattice give you diamond. Same element, opposite extremes: softest mineral versus hardest, conductor versus insulator. The molecule that proved structure matters as much as composition. The Science Behind Graphite Graphite consists of sp2 hybridised carbon atoms arranged in planar hexagonal sheets. Each carbon
