WebThe bond length is 0.142 nm. The bonds between atoms of carbon in the layers of graphite may be strong, but the bonds that are formed by carbon atoms between layers are quite weak. These atoms are held together by Van Der Waal's forces. This kind of attraction is caused by shifts in the cloud of electrons surrounding carbon nuclei.
