8/8/2020· Structure of carbon allotropes When an element exists in more than one crystalline form, those forms are called allotropes; the two most common allotropes of carbon are diamond and graphite.The crystal structure of diamond is an infinite three-dimensional array of carbon atoms, each of which forms a structure in which each of the bonds makes equal angles with its neighbours.

Which is stronger- covalent or ionic bonds??? - The …

However some covalent compounds can exist as a giant covalent network, such as in diamond. This is where all carbon atoms are bonded to 4 other carbon atoms and this makes a very strong compound with extremely high melting points.However, in terms of the pure strength of the intra-molecular bonds (between atoms in a molecule), covalent bonds are stronger.
