In graphite, the bonds are sp2 orbital hybrids as well as the atoms sort in planes, with Every certain to three nearest neighbors, a hundred and twenty levels apart. In diamond, These are sp3 and the atoms kind tetrahedra, with Each individual bound to 4 closest neighbors.[four][five] Tetrahedra are rigid, the bonds are powerful, and, of all recognised substances, diamond has the best number of atoms for each device quantity, Which explains why it's equally the toughest and also the least compressible.
