The conductance of electricity also high density, but more importantly sales electricity is the flow of electrons it requires that only minimal energy be required to excite from the valence band conductance band. In metals this band gap is is extremely small allowing large number of electrons to be excited to the conductance band by relatively little energy. Suffice it to say, no metal is a gas under any reasonable condition......

At atmospheric pressure, air and other gasesare poor conductors(Insulators) of electricity. Because, they don't have any free electrons to carry current. But, once the free electrons are produced in gasby ionization (they become plasmas), electric discharge occurs
