Metals conduct beaus of delocalized electrons. Band theory is similar to thinking about molecular orbitals the concept from chem 1. When two atoms bond their atomic orbital mix and form molecular orbitals. But in band theory it is on a much larger scale 10^23 atoms or avagadros number. Insulators have big gaps in the connection band and semi conductors have small gaps in the connective bands.

I wonder what other electric words might prove useful here. I'm thinking explicitly about something like rhetoric's "conductive" character. Can rhetorical practice be thought through conduction?
