In diamond's structure, each carbon atom is covalently bonded to four other carbon atoms by very strong bonds forming a 3D tetrahedral shape.

The structure is highly symmetrical and the C-C bonds are very strong, which is why it is the strongest naturally occurring substance. The structure of graphite is different to the structure of diamond. Rather than a carbon atom bonding to four other carbon atoms, each atom in graphite is bonded to three other atoms.

Jul 24, 2008. The answer lies in the different atomic structures of diamond and graphite. Graphite forms in layers or sheets where the carbon atoms have strong bonds on the same plane or layer, but only weak bonds to the layer above or below. The carbon atoms in diamond, on the other hand, have strong bonds in.

Each carbon atom within the graphene layer has three of these sigma atomic orbitals, which combine with similar orbitals of adjacent carbon atoms forming the molecular bonds that hold the layer together (see sp2 bonding in the organic chemistry section). In contrast, the carbon atoms of the diamond structure each have 4.

INTRODUCTION TO CHEMICAL BONDING. Why is knowledge of chemical bonding important? Chemists can use the theory of structure and bonding to.

Diamond has the highest hardness and thermal conductivity of any bulk material while remaining an electrical insulator. The structure of diamond is based on a continuous network of tetrahedrally bonded carbon atoms in which extremely strong covalent bonds are formed between -hybrid orbitals. The C–C bond length is.
