Gold is not the best electrical conductor. Silver is actually a better conductor. Gold is generally thought of as a better material to use because of it corrosion resistance. The reason why gold is conductive is the same reason why almost all conductive solids (and a few liquids) are conductive. They have free electrons (valence electons). Think of an atom. Around the nucleus, orbit the electrons. The electrons form into rings with a specific amount of electrons allowed in each ring. To be in good ballance, the atom wants to have the last ring to be completely full. So, elements that have a few extra electrons like Au and Ag try to get rid of them. Thus making them conduct electricity. (in laymans terms)

Yes. If you ignore "superconductors", gold is about the best conductor of heat and electricity. Comment Silver is the best conductor, followed by copper, then gold.

It is the 3rd best electrical conductor

Yes, gold is a very good conductor

For both electrical and thermal conductivity, Copper is the best of the three, then Gold, then Tungsten.

No, gold is not the best conductor. At room temperature, silver is a slightly better conductor. The best electrical conductors are the so-called superconductors, which are materials that only exhibit the property of superconductivity at very low (cryogenic) temperatures. When exhibiting the property of superconductivity, they have a resistance of zero.
