WebGraphite: Graphite is composed of multiple flat layers of carbon atoms stacked on top of each other. The layers are attracted to each other by weak London dispersion forces, which explains why graphite flakes easily. Graphite is also an electrical conductor. Graphene is the only form of carbon (or solid material) in which every atom is available for chemical reaction from two sides (due to the 2D structure). Atoms at the edges of a graphene sheet have special chemical reactivity. Graphene has the highest ratio of edge atoms of any allotrope. Defects within a sheet increase its chemical reactivity. The onset temperature of reaction between the basal plane of single-layer graphene and oxygen gas is below 260 °C (53…
