In simple terms, graphene, is a thin layer of pure carbon; it is a single, tightly packed layer of carbon atoms that are bonded together in a hexagonal honeycomb lattice. In more complex terms, it is an allotrope of carbon in the structure of a plane of sp2 bonded atoms with a molecule bond length of 0.142 nanometres.
HET618-M07A01: Synthesis of Complex Organic Molecules: Organic Molecules in Space PAGE 11 OF 57. In the core of red giants and AGB1 stars, the helium fuses to form carbon, and carbon and helium. fuse to form oxygen. Carbon and oxygen are the most abundant elements produced in stars.
