Why do xenon/krypton have relatively high electronegativity

[psuedoben]

what sets xenon and krypton apart from the other noble gasses that enables them to have higher electronegativites?

I[/PLAIN] don't know, but I do know how to google...

haha thanks for the attempt, i too am familiar with google, but i still haven't found any satisfying answers simply through typing it in on the web.

Well the fact is that we as a species still have much to learn, for there are many things that we don't know. So if you can't find an answer, maybe it has not been solved yet...

So if you can't find an answer, maybe it has not been solved yet...

Or, more likely, the only acceptable answer is "that's what you get when you measure/calculate, possible explanations are too handwavy to make sense".

Please remember that science doesn't answer question "why?". Science answers question "how?". We sometimes try to explain "why" using our knowledge about "how", but it is always a risky business.

Um, but the EN of the noble gases decreases down the table!

Noble gases do not have electro negativity. But E.N decreases down a group and increases left to right across a period. Can you give reference for your question?

I have come across a link

This may explain everything about your question.

Noble gases do not have electro negativity.

Of course they have. E.g. Mulliken's EN can be derived from measured electron affinities and ionisation energies, see

Yeah, okay, is that answer explained in link on post #8 correct?
