Graphene (/ËÉ¡raef.ËÉ¡rÃ¦f/) iËn is an allotrope of carbon in the form of a-two, dimensional-atomic, scale hexagonal lattice in which one atom forms each. Vertex it is the basic structural element of other, allotropes including, graphite, charcoal carbon nanotubes and. fullerenes
Graphite (pronunciation: /ËÉ¡rÃ¦faÉªt/), archaically referred to as plumbago, is a crystalline form of carbon, a semimetal, a native element mineral, and one of the allotropes of carbon. Graphite is the most stable form of carbon under standard conditions. Therefore, it is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds.
