Electrical conductors:
Pure metals and the best conductors. Copper is the most common material for electrical wiring, and gold for high-quality surface-to-surface contacts,the reason is that it prevents corrosion because it doesn't react with Oxygen.

However, there are also many non-metallic conductors, including graphite, solutions of salts, and all plasmas

Examples:
Silver
Copper
Gold
Aluminum
Iron
Lead
Platinum
Tin
Tungsten
Zinc
Mercury
Graphite
Salt solutions
Plasma


Thermal conductors:
Most metals are good thermal conductors (as above examples), but the best thermal conductors of all are diamond and carbon nanotubes. The reason for this is that both diamond and carbon nanotubes contains strong molecular bonds in very regular order making it easy for molecular vibrations to travel quickly and efficiently through the materials.

Metals make good electrical and heat conductors.

Most metals are good conductors, gold is good but expensive, copper is another and relatively inexpensive. Many multi layer ceramic ceramic capacitors, used in electronics, use palladium.

These are Gold, Silver Copper and aluminium Because these have very low ionisation energies and can easily loose electrons which carries electricity.

I make semiconductor wafers/IC's out of Silicon. Gold is often used as a deposit in many applications.

copper of course, cheap and at reach.
although it is getting much more expensive these days, as i hear in the economic news!!
