The previous scale was developed by the Nobel laureate Linus Pauling. His version, according to the authors, is not
Electronegativity is the ability of atomsattract electrons when bonding with other atoms. It depends on the distance between the nucleus and the valence electrons and on how close the valence shell is to complete.
To our great surprise, we saw that Pauling's scale is inconsistent with either theoretical or experimental bond energies. Moreover, it was known in the chemical
literature, but a satisfactory solution has not been proposed.

The authors note that Pauling's table is correct fornormal temperatures and pressures, however, in experiments at high pressures and in experiments with substances whose electronegativity of atoms is very different, the predictions of Pauling's theory differ significantly from the observational data.
Using new formulations, Russian scientistsprepared a new scale of electronegativity of elements. According to the developers, it works equally well at low and high pressures and correctly predicts the nature of the interactions of both atoms that are similar to each other and elements from opposite ends of this scale.
