WebSep 9, 2024 · Graphene is a single isolated layer of graphite. It has a 2D arrangement and the carbon atoms are bonded in a hexagonal (honeycomb) structure in a continuous sheet. On the other hand, … Graphene is an allotrope of carbon consisting of a single layer of atoms arranged in a hexagonal lattice nanostructure. The name is derived from "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon contains numerous double bonds. Each atom in a graphene sheet is connected to its three nearest neighbors by a strong σ-bond, and contributes to a valence band one electron that extends over the whole sheet. This is the sam…
