The previous scale was developed by Nobel laureate Linus Pauling.
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 no satisfactory solution was proposed.Artem Oganov, one of the authors of the work, professor at the Skolkovo Institute of Science and Technology
The authors note that Pauling's table is correct at normal temperatures and pressures, but in experiments at high pressures and in experiments with substances whose electronegativity of atoms varies greatly, the prediction of Pauling's theory differs 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.
