Diamond, graphite and fullerenes are crystalline forms of carbon. Explain
Answers
I hope this will help you and if not sorry ☺
"""Carbon is present in crystalline forms and also exists in an amorphous form.
Carbon are of different forms which are called allotropes. Example: diamond, graphite fullerene. Many atoms are linked in a crystal in a repeated pattern that can contain thousands of atoms.
For each carbon form, in the crystal, the atoms arrangement differs and explains why the various forms have different properties.
Diamond is a carbon form where each carbon atom is connected to four additional carbon atoms. This forms a strong, rigid and three-dimensional structure.
It is the hardest material which is formed naturally and cannot be broken easily.
Graphite is a crystalline carbon form where each carbon is connected to three additional carbon atoms. In each single layer of carbon atoms have strong bonds but only weak bonds are present in between layers.
The weak forces of attractions between the layers allow the layers to slide over each other, so that graphite is relatively slippery and soft.
Another form of a carbon is a fullerene where the arrangement of carbon atoms are in a sphere shape.
Each sphere has 60 carbon atoms and each carbon is linked by a single covalent. The bonds which are present in carbons are relatively weak."""
