Graphene metallic bond
WebGraphite is amongst the most commonly known and naturally found allotropes of carbon. It is comprised of a layered structure having sp 2 hybridized carbon atoms with one free electron capable of forming coplanar and interplanar bonding. The layers, stacked through secondary bond forces, can slide over one another [14].In other words, graphite … WebThe bonding also explains the hardness of diamond and its high melting point. Significant quantities of energy would be needed to separate atoms so strongly bonded together.
