A conductor
Metals which have free valence electrons conduct electricity and heat. thus they are good conductors.
electric circuit
The blunt answer is that ALL materials can potentially conduct heat and electricity (metals, air, water, human bodies, cloth, wood, even rubber, etc), but require the right conditions. A GOOD conductor is one that can transmit heat or electricity or both VERY EASILY under standard temperature/pressure conditions. There are many, many GOOD conductors out there and too numerous to name on this answer board.
insulator; I think porcelain.hopefully.
If your meaning what carries electricity to an electrical object then the answer is electrons. Electrons are like parcels, they carry electricity to the object to make it work

Copper
A Liquid that conducts electricity and is decomposed in the process is called electrolyte.
Yes, gold conducts electricity. In fact, it's an excellent electrical conductor. Coupled with its resistance to corrosion, it finds broad use in modern electronics, to name just one application.
A substance that conducts electricity is a conductor. There is no special name for one that is solid; if you need to specify that it is solid, just call it a "solid conductor".
Graphite which is a crystalline allotrope of carbon conducts electricity because of the presence of free mobile electrons occassioned by their planar structure.

Static Electricity.
