One of the reasons why non reactive metals are good conductors is that they are good at staying as metals.
Metals are good conductors because they have unfilled space in the valence energy band.
Metals make good conductors because the outer electrons of their atoms are loosely attached, and the electrons can drift through the metal when a voltage is applied. Some materials have all their electrons firmly fixed in place, so they do not conduct electricity well.

I believe silver is the better conductor of the two metals, but sometimes they seem to use gold instead of silver. Could this be because the electricity passes on the surface of the metal and silver's surface is more easily tarnished than that of gold which doesn't tarnish?
Practical metals do not have a perfect lattice because of impurities and because of the deviation of atoms about their mean position due to lattice oscillations (Debye waves).
