WebIt is very strong because of its large regular arrangement of carbon atoms joined by covalent bonds. Like graphite, graphene conducts electricity well because it has delocalised electrons that are ... WebNov 2, 2024 · It is a single atomic layer of graphite (which is used, among other things, for pencil tips). Graphene is special because of its sp2 hybridization and extremely thin atomic thickness (0.345 nm), properties that make it remarkably strong (about 200 times stronger than steel) as well as an excellent conductor of heat and electricity.
