Symmetry
Abstract Every real solid is bounded by surfaces. Nonetheless, the model of an infinite solid which neglects the presence of surfaces works very well in the case of many physical properties. The reason is, firstly, that one usually deals with properties, such as transport, optical, magnetic, mechanical or thermal properties, to which all the atoms of the solid contribute more or less to the same extent, and, secondly, that there are many more atoms in the bulk of a solid sample than at its surface, provided the solid is of macroscopic size. In the case of a silicon cube of 1 cm3, for example, one has 5 √ 1022 bulk atoms and 4 √ 1015 surface atoms.
