Why can we break graphite when it is made of graphene which is like 40 times more harder than diamond?(according to google)
In: Chemistry
Graphene is essentially a 1-atom-thick “sheet” of carbon. The bonds between the carbon atoms in this sheet are stronger than the bonds between carbon atoms in diamond. However, graphene is a two-dimensional material, while diamond is three-dimensional. So, while graphite *is* made of graphene, it is really made of multiple sheets of graphene that don’t stick to each other very well, which makes it easy for us to pull one sheet away from another and break graphite.
