I have looked at this question and most of the responses. Nowhere is these
is there a good quantitative definition of electronegativity. My short term
memory is not that great, but I do remember seeing something to indicate
that it is measured in electron-volts.

Without knowing how to calculate it or to measure it, we are dealing with
pre-Lavoisier concepts. How do you measure electronegativity experimentally?
