A fullerene is an allotrope of carbon whose molecule consists of carbon atoms connected by single and double bonds so as to form a closed or partially closed mesh, with fused rings of five to seven atoms. The molecule may be a hollow sphere, ellipsoid, tube, or many other shapes and sizes. Graphene (isolated atomic layers of graphite), which is a flat mesh of regular hexagonal rings, can … WebThe 60 carbon atoms form what is called a truncated icosahedron, which literally looks like a soccer ball. It consists of 12 regular pentagons and 20 regular hexagons. The C60 molecule does not bond readily to other atoms or molecules, as all bonds are to another carbon atom.
