Diagram of graphene structure
WebGraphene is a parent form of all graphitic structures of carbon: graphite, which is a three-dimensional crystal consisting of relatively weakly coupled graphene layers; nanotubes, which may be represented as … WebGraphene is a single layer (monolayer) of carbon atoms, tightly bound in a hexagonal honeycomb lattice. It is an allotrope of carbon in the form of a plane of sp2-bonded atoms with a molecular bond length of 0.142 nanometres. Bonding [ edit] Carbon orbitals 2s, 2p x, 2p y form the hybrid orbital sp 2 with three major lobes at 120°.
