There are dozens of electronegativity (X) scales published. Excluding the ones proposing simple correlations between properties, they are summarized here. The different intents to evaluate and regulate the X scales are displayed. A balance was made, allowing us to appreciate: the great diversity of ideas generated over the years; the scales tendency is not so different when comparing with Pauling's one; and no one is 100% successfully in a given application. This permits the authors to suggest that X is not a property, but a behavior. To find a universal X scale at this moment seems difficult.
