WebThe sigma bonding system acting within a single graphene layer is exceedingly strong. In fact, it is probably the strongest 2 dimensional network structure known, and is the structural backbone of all carbon/graphite fibers, and carbon nano-tubes. The strength of the sigma bond in carbon is also illustrated by the high hardness of diamond. WebThe bonds are all equivalent and the bonding electrons are, more or less, “pinned” between the carbon and hydrogen nucleus. In order to minimize repulsive forces, the …
WebOct 9, 2007 · Unlike diamond, graphite can be used as a lubricant or in pencils because the layers cleave readily. It is soft and slippery, and its hardness is less than one on the … WebGraphite. Again the carbon atoms are bonded together to make a giant structure but in this case all of the carbons are bonded to only three neighbour and are sp 2 hybridised. As the sp 2 hybridisation results in planar structures, there are giant 2 dimensional layers of carbon atoms and each layer is only weakly linked to the next layer by Van der Waal's forces.
