best insulator
why it's said that the best insulator could be found in the rare gas group?
what's the theory that this conclusion(best insulator-rare gas group) bases on?
because of the fulfillment of outter shell electrons so that's neither easy to lose e- or gain e- and therefore the best insulator?

This is an answer that can be bent in different ways depending on the rest of the question. Best electrical or thermal insulator? Best of the
elements or of everything we use? If electrical, best with regard to leakage current, or breakdown voltage?
Xenon is a pretty good thermal insulator too, its monatomic and very high molecular mass. Its extremely expensive though and so isnt used widely (at
all?)
The best insulator of all is arguablly a perfect vacuum, both for thermal and electrical purposes. In terms of solids the one that takes the prize is
probably teflon. The gas most often used to insulate high voltage equipment (other than air or nitrogen) is probably SF6 but I dont know how this
compairs electrically to nobel gasses.
