Describe graphene as a single layer of graphite.

In the subtopic Graphene and fullerenes, this learning objective focuses on describe graphene as a single layer of graphite. Within Structure and bonding of carbon, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include graphene. Graphene means a single layer of graphite consisting of carbon atoms arranged in a two-dimensional hexagonal lattice. Avoid students often describe graphene as having multiple layers of carbon atoms instead of a single layer; instead emphasize that graphene is specifically defined as a single layer of graphite, highlighting its unique properties that arise from this structure. For exam answers, remember that graphene is a single layer of graphite, which helps in visualizing its properties.
