A good introduction to graphene with diagrams and literature survey of the field can be found in [1,2]. It can be seen from [1] that research on graphene is currently pursued in many scientific institutions, and notably by the Geim group [2]. The structure of graphene is presently represented as a ball and stick model [3]. 4.2.3.3 Graphene and fullerenes Key opportunities for skills Graphene is a single layer of graphite and has properties that make it useful in electronics and composites. Students should be able to explain the properties of graphene in terms of its structure and bonding.
Graphene is a single layer of graphite and has properties that make it useful in electronics and composites. Students should be able to explain the properties of graphene in terms of its structure and bonding. Fullerenes are molecules of carbon atoms with hollow shapes. The structure of fullerenes is based on hexagonal rings of carbon atoms but they may also contain rings with five or seven carbon atoms.

Graphene is a crystalline allotrope of carbon with 2-dimensional properties. Its carbon atoms are densely packed in a regular atomic-scale chicken wire (hexagonal) pattern. Each atom has four bonds, one σ bond with each of its three neighbors and one π-bond that is oriented out of plane.

Properties of graphene in terms of structure and bonding

:A visual depiction of the structure of a layered, microscopic segment of graphene. At approximately 200 times stronger than structural steel, given enough layers, graphene would be both harder and stronger than any material ever created, opening the possibility for products and structures that are a fraction of the weight and an exponent of the strength of any existing currently.

Seven sheets of straightforward revision questions. Written to provide simple recall test of what students have learned and need to learn (to reassure them as much as anything). Taken pretty much directly from the AQA 9-1 GCSE syllabus - Bonding, Structure and The Properties Of Matter. Answer sheets are included.

The term “graphene” is also not used to describe the single layer of graphite until 1987 by S. Mouras . Since then graphene was commonly regarded as a virtual expression of unit structure in graphite and subsequent CNT in calculation and simulation, instead of a realistic form of carbon nanomaterial.
