Why would someone do that experiment? I don't think you'll find it.
Anyway, it is well known that you can have a negative resistance behavior in some gas discharge configurations. That is why fluorescent lights have ballasts, for example. I find the questions about negative conductivity confusing. What do you really want to know

My question might be a bit confusing. I thought some one may have conducted this experiment out there. Considering that metal vapors are very light weight relative to solid copper wires: I thought why not design an electric motor where instead of rotor windings made of copper you have tubes filled with this metal vapor. By doing so, the rotor would be substantially lighter and thus the motor might rotate faster or less energy will be wasted. That's why I want to know the electrical conductivity of metal vapors at suitable conditions. I am fully aware that there are metals that are far lighter than copper (aluminum) but why not go even lighter? What conductive gases experience positive resistance behavior? Potassium or Caesium vapors don't experience that? Thank you for taking the time to answer...
