In graphite, the bonds are sp2 orbital hybrids and also the atoms sort in planes, with each certain to 3 nearest neighbors, one hundred twenty levels aside. In diamond, They are really sp3 and also the atoms variety tetrahedra, with each bound to four nearest neighbors.[four][five] Tetrahedra are rigid, the bonds are powerful, and, of all acknowledged substances, diamond has the best amount of atoms per unit quantity, Which is the reason it's both the hardest and also the minimum compressible.
