What group on the periodic table has the poorest conductors?

The group on the Periodic Table with the poorest conductors is Group 18, the noble gases. These elements, including helium, neon, argon, krypton, xenon, and radon, are characterized by their complete valence electron shells, which make them chemically inert and non-metallic. As a result, noble gases do not possess free electrons to facilitate electrical conductivity, making them Excellent insulators rather than conductors.
