Each carbon atom is in a rigid tetrahedral network where it is equidistant from its neighboring carbon atoms. Molecular Structure: In diamond, the carbon atoms are covalently bonded to one another producing a three-dimensional network solid. In diamond, carbon atom occupies FCC lattice points as well as alternate tetrahedral voids. This is because carbon has four valence electrons to form four covalent bonds to 4 other other carbon atoms. High-resolution electron microscopy. Graphite consists of carbon atoms covalently bonded together in a layer made up of hexagons, like chicken wire. Do it in the following stages: Practice until you can do a reasonable free-hand sketch in about 30 seconds. C-C single covalent bonds. How long can you leave a 12 week old puppy alone? Where are diamonds found in the world? So the structure of diamond is like a 3D structure. The sheets of carbon become bonded by weaker intermolecular forces. In a diamond structure, there are atoms at each corner and alternate tetrahedral voids. While the first known example was diamond, other elements in group 14 also adopt this structure, including α-tin, the semiconductors silicon and germanium, and silicon/germanium alloys in any proportion. The fluorite structure: all tetrahedral sites occupied Fluorite, CaF 2 , having twice as many ions of fluoride as of calcium, makes use of all eight tetrahedral holes in the CPP lattice of calcium ions (orange) depicted here. The four possible structures of diamond 3. It is hardest parallel to its octahedral planes and softest parallel to its cubic planes. Notice that each carbon atom is bonded to four other carbon atoms.

Diamond's cubic structure is in the Fd3m space group, which follows the face-centered cubic Bravais lattice. A tetrahedron is composed of four triangular faces. Diamond might be better for this because it is harder and could require more energy to shatter. has a very high melting point (almost 4000°C). The carbon atoms in diamonds are arranged in a strong, tetrahedral structure. p.s. Because of its tetrahedral structure, diamond also shows a great resistance to compression. Colored diamonds contain interstitial impurities or structural defects that cause the coloration; pure diamonds are perfectly transparent and colorless. Do diamond and graphite have the same molecular structure. The carbon tetrahedra are covalently bonded, accounting for diamond's extreme hardness. These symmetry operations are usually denoted as point operations, since they leave at least one point of the lattice invariant, which is not the case for translations.
