Diamond is a solid kind of pure carbon with its atoms organized inside a crystal. Stable carbon comes in several forms generally known as allotropes depending on the sort of chemical bond. The two commonest allotropes of pure carbon are diamond and graphite. In graphite, the bonds are sp2 orbital hybrids and also the atoms variety in planes, with Just about every certain to 3 closest neighbors, 120 degrees aside. In diamond, They may be sp3 along with the atoms sort tetrahedra, with Just about every certain to four nearest neighbors.[four][five] Tetrahedra are rigid, the bonds are solid, and, of all recognised substances, diamond has the best quantity of atoms for each device quantity, Which explains why it can be both the toughest and the minimum compressible.
