Concerning Electronegativity as a Basic Elemental Property and Why The Periodic Table is Usually Represented In Its Medium Form

Abstract

Electronegativity – described by Linus Pauling described as "The power of an atom in a molecule to attract electrons to itself" (Pauling in The nature of the chemical bond, 3rd edn, Cornell University Press, Ithaca, p 88, 1960) – is used to predict bond polarity.

There are dozens of methods for empirically quantifying electronegativity, including:

Indeed, there are such strong correlations between numerous atomic parameters—physical and chemical—that the term "electronegativity" integrates these correlations into a single dimensionless number between 0.78 and 4.00 that can be used to predict/describe/model much of an element's physical character and chemical behaviour.

The design of the common and popular medium form of the periodic table is in large part determined by four quantum numbers and four associated rules. However, adding electronegativity completes the construction so that it displays the multi-parameter periodic law operating in two dimensions, down the groups and across the periods, with minimal ambiguity.
