SALAS-BANUET, Guillermo et al. The importance of being chemical affinity. Part VI: The harvest. Dyna rev.fac.nac.minas [online]. 2015, vol.82, n.190, pp.13-22. ISSN 0012-7353.

The quantitative scale of electronegativity, obtained by Linus Pauling, as a result of qualitative electron affinity background, generated multiple different and interesting proposals until today, which have proved to be the effort of ingenuity to get a universal concept of affinity, which has resulted incomplete. Thermodynamics, specifically its thermochemical branch, has offered an explanation, which has been accepted by The International Union of Pure and Applied Chemistry (IUPAC), as incomplete as the former. In both cases, it is thought that the error is in regard to affinity as a property, rather than a behavior.

Keywords : Affinity; Electronegativity; chemistry; history; thermodynamics.
