“…Chemical bonds cannot be found at the bottom and right sides of the CT, as well as at M and I vertices (this is why these sides are shown as dotted lines) due to the fact that C C cannot be equal 0. In the same direction work is underway in the United States and Europe, but there are no attempts to quantify the metallic character, to develop a single model of chemical bonding [14][15][16][17][18][19][20] aiming at the creation of a truly chemical system in the form of a Chemical triangle [12,13]. As a result, the use of this basic scientific innovation for the first time made a symbiosis of the approach of two outstanding Russian chemists: D. I. Mendeleev's periodic system of atoms (composition -property) and A. M. Butlerov's theory of chemical structure of matter (composition -chemical structure -property).…”

It was shown that the traditional approaches to understanding the notion of “energy” as a work or a physical quantity are outdated. For example, R. Feynman noted that “today’s physics does not know what energy is.” Therefore, even now, some researchers believe that “by and large, the concept of energy… is artificial, because unlike matter, of which we can say that it exists, energy is the fruit of human thought.” In contrast to these ideas, the authors showed that energy, like matter, objectively exists in various forms (energy continuum), which differ in structure, and is able to perform different types of work, to determine the forms of interaction and movement of matter in various material systems (substances, material bodies and megamaterial systems). A new scientific foundation for systematization and quantitative evaluation of energy characteristics of chemical compounds was proposed. It is based on a comprehensive assessment of contribution of chemical compounds’ composition and chemical bond type in line with a chemical bond’s unified model and the “System of chemical bonds and compounds” (SCBC). As a result of using this basic scientific innovation, the symbiosis of Mendeleev’s periodic table of atoms (composition – property) and SCBC (composition - chemical bond and structure – property) was realized for the first time. The foundation was laid for creating a database on systemic digitalization and evaluation of energy stored in various chemicals (natural gas, coal, oil, peat, wood, etc.) and the most effective ways of extracting it from these.

“…Pettifor's ENs were scaled so as to equal Pauling's values for Be through F and, curiously enough, for most elements are close to the solid-state ENs of Batsanov (1975Batsanov ( , 1982. Sproul (1994) constructed a map in the Á and coordinates, locating the regions of covalent, ionic and metallic compounds. Bialon et al (2016) suggested a threedimensional structure map in the coordinates of band-filling, atomic volume and EN according to Pauling (1932), Mulliken (1934), Allred & Rochow (1958) and Martynov & Batsanov (1980), which predicts (with 86% probability) the correct crystal structures of binary and ternary compounds of sp elements with transition (d) metals.…”

Electronegativities (EN) of 65 elements (H to Bi, except lanthanides and noble gases, plus U and Th) in solids were derived from various observed parameters, namely, bond energies in solids, structural geometry, work functions and force constants, yielding a set of internally consistent values. The solid-state electronegativities are generally lower than the conventional (`molecular') values, due to different coordination numbers and electronic structure in a solid versus a molecule; the decrease is stronger for metals than for non-metals, hence binary compounds have a wider EN difference and higher bond polarity (ionicity) in the solid than in the molecular (gaseous) state. Under high pressure, the ENs of metals increase and those of non-metals decrease, the binary solid becomes less polar and can ultimately dissociate into elements.

“…Sproul evaluated 15 EN scales by the ionic, covalent, or metallic property for the 311 binary compounds, and proposed that a comprehensive EN scale would have the ablity to not only predict the nature of a chemical bond but also indicate the incorrect bond type specification [20] . Pearson suggested that different EN scales have different applications, and each scale is correct within its own area of application [21] .…”
