“…Table 1 lists the ENs from [ 14 ], improved in some cases by the use of up-to-date values of ionization potentials for polyvalent elements [ 18 ]. Mulliken’s approach was developed further by many authors (see reviews in [ 19 , 20 ]).…”

Historical development of the concept of electronegativity (EN) and its significance and prospects for physical and structural chemistry are discussed. The current cutting-edge results are reviewed: new methods of determining the ENs of atoms in solid metals and of bond polarities and effective atomic charges in molecules and crystals. The ENs of nanosized elements are calculated for the first time, enabling us to understand their unusual reactivity, particularly the fixation of N2 by nanodiamond. Bond polarities in fluorides are also determined for the first time, taking into account the peculiarities of the fluorine atom’s electronic structure and its electron affinity.

“…[11] Many EN scales have been developed from time to time, both qualitatively and quantitatively, but EN has yet to have a widely recognized understandable model that characterizes it. [12] EN has been utilized in a variety of areas. There is no limit to how broadly it may be defined.…”

An FSGO based Electronegativity Scale invoking the Electrophilicity Index

Electronegativity is an important chemical construct that plays a pivotal role to explain several chemical, biochemical and physicochemical phenomena. The study of this periodic descriptor is still considered an active domain of research, and a number of scientists are involved to propose different scales of electronegativity based on experimental findings and theoretical concepts. In this study, we have proposed a model to compute atomic electronegativity values of 103 elements based on the Floating Spherical Gaussian Orbital approach invoking the atomic electrophilicity index as a descriptor. The computed electronegativity scale observes the periodic trend and justifies many chemical phenomena. Molecular electronegativity values have also been computed using the computed atomic electronegativity data and utilized to justify the Electronegativity Equalization Principle. In order to validate our proposed model, internuclear bond distances for some molecules have been deduced in terms of our computed atomic electronegativity data. A strong correlation with experimental counterparts proves the efficacy of our proposed model.

Wavelength‐dispersive X‐ray fluorescence (WD‐XRF) is a somewhat conservative technique, staying in one raw with the traditional X‐ray diffraction method. It seems even unfashionable to apply such heavy, huge, energy‐consuming, and totally costly instruments nowadays. Nevertheless, the good stability and easy quantification give that method the prevalence in large laboratories handling such fields as metallurgy, geological analyses, archaeometry, pollution, and environmental monitoring. The good spectral resolution for low‐energy X‐rays enables both the analyses of light elements up to Be and the chemical speciation. The steady progress of the WD‐XRF in the following, hardly expected fields is one of the most exciting questions: □ mapping option, which has been earlier considered unfeasible and now is executed, with especially good spectral resolution; □ nontrivial representation of results in the energy units; □ application of Artificial Intelligence (AI) for pattern recognition or quantification, sometimes without the need for the registration of the searched element; □ new possibilities of the dynamical measurements of the Pauling electronegativities for the elements of I and II Group of the Periodic System.
