Best ResponseYou've already chosen the best response.1Well I would look at scientific papers done by linus pauling (amazing scientist) on the subject as he is the one who first proposed electronegativity. I wish I could be of more help I hope someone comes along and explains it as it is an interesting question

Best ResponseYou've already chosen the best response.1Electronegativity is just a number for each element. You can find it on a Periodic Table that includes electronegativity.

Best ResponseYou've already chosen the best response.1This question is more in relation to how one would measure it in a laboratory I would assume. Which is an interesting question.

Best ResponseYou've already chosen the best response.0The question was directed to both how it is measured in a laboratory as well as how to figure out the electronegativity difference. So both answers are correct.

Best ResponseYou've already chosen the best response.1I have yet to read this article so I do not know if it contains your answer I will search a little more and I plan on reading them later

Best ResponseYou've already chosen the best response.0yes i would also just use a periodic table of elements. general rules are the more top and to the left, the more electronegetive. there are exceptions but its a good rule.

Best ResponseYou've already chosen the best response.0Electronegativity doesn't have an umabiguous and natural definition, like ionization potential or electron affinity. It's a madeup quantity, like "percent ionic character" or "percent metallic character" or "how poisonous" that is meant to convey an overall impression of a whole basket of underlying welldefined physical and chemical properties. What happens is that various people have devised various definitions of electronegativity, which they hope result in a scale that best captures the bonding behaviour of atoms (which is the point of the EN scale). You then follow those defintions to calculate the EN. For example, the earliest proposal for electronegativity was that by Linus Pauling, and he gave a definition that involved comparing the first ionization energies of the elements. That would only give you a relative number, so you still had to define at least one electronegativity arbitrarily, and then measure every other number relative to that. Pauling chose to define the EN of fluorine as 4.0, and then measure everything from that, and that gives you the Pauling EN scale. There have been a number of other scales proposed, but unless this stuff fascinates you I think most people just stick with Pauling, since the precise numbers don't matter a whole lot  you're just interested in the broad trends.
