WebIn this video, we explore the diamond and graphite which are two allotropes of solid carbon and we compare their structure and properties. Allotropes are di... WebThe structure of the crystal has a cubic elementary cell, looking like a “ Giant molecule.” Graphite, on the other hand is made up of many carbon ring layers (graphene – see later) stacked together, with the elementary cell being of hexagonal type. Unlike diamond, graphite has zero bandgap, which conducts heat and electricity very well.
