Pearlite has a diamond pyramid hardness (DPH) of approximately 200 kilograms-force per square millimetre (285,000 pounds per square inch), compared with a DPH of 70 kilograms-force per square millimetre for pure iron. 6. According to the VSEPR model, the progressive decrease in the bond angles in the series of molecules CH4, NH3, and H2O is best accounted for by the, increasing the number of unshared pairs of electrons, The best explanation for the fact that diamond is extremely hard is that diamond crystals, are giant molecules in which each atom forms strong covalent bonds with all of its neighboring atoms.
