How to calculate electronegativity for cadmium oxide?

Answer 1

I would suggest first to consider Linus Pauling´s classical book "The nature of the chemical bond" to check whether (and if so, ¿how?) the electronegativity concept is applicable to compounds. It may also be mentioned that more recently A. Miedema and collaborators developed an empirical model for the energetics of alloys which involves an electronegativity-related parameter, but again the scale is for elements...
