How do I figure out the conductivity or conduction band for an element?

Note: This might not be absolutely correct (it was a long time since I took this course)
I think it is related to the energy difference between the filled and the vacant electron energy level bands. For conductors (metals) the energy levels overlap and electron flow is easy; for semiconductors they don't overlap, but there is a narrow separation which allows a few to flow (heating a semiconductor slightly raises the filled energy level bands (narrowing the band gap) and increasing conductivity up to a certain point. For non conductors, the separation (band gap) is so large essentially no electronflow occurs. I'm not certian how they determine this experimentally.

Well, you can use a table for it. You can look one up online. Here is one you can use.
