To summarize, our fairly complete analysis of single chemical bond is based entirely on the multiparticle description, both in the first and second-quantization schemes. Both of the descriptions are equivalent, but within the second of them it is possible to relate it directly to the particle language. In general, the approach may represent a starting point to a precise experimental resolution of the bond factors, as well as to quantify their specific features in more complex situations. Also, the method bridges the atomic and molecular aspects of the chemical bond in precise multiparticle categories. Analogous analysis may be carried out for the resolution of covalent bonds evolution into ionic bonds and vice versa.
