A conductor carries electricity and is made of such a material that can conduct electrons. Like copper for instance which is the best or close to the best material for carring electrical currents...Insulators on the other hand prevent the passing of electrical currents: like plastic or rubber which are used to insulate wire,switches etc.
The best electrical conductor is silver, followed by copper. Gases can be made to conduct well when they're ionized.
Metals are known to be good conductors of heat as well as good conductors of electricity. Diamond is an exception though, being one of the best thermal conductors but a very poor electrical conductor.
The worst conductor would be rubber and the best metallic conductor would be silver
Most familiar conductors are metallic. Copper is the most common material used for electrical wiring. Silver is the best conductor, but is expensive. Gold is used for high-quality surface-to-surface contacts. Aluminium too is a good conductor.

Oxygen. Carbon as diamond is a good electrical insulator, (graphite is an electrical conductor), silicon is a semiconductor so has limited electrical conductivity and aluminium is a metal and a good electrical conductor.
Silver is the best electrical conductor in the periodic table, next is copper. Copper is used in wires because it is nerly as good as silver, but is far cheaper.
Metals are known to be good conductors of heat as well as good conductors of electricity. Diamond is an exception though, being one of the best thermal conductors but a very poor electrical conductor.
The best electrical conductor known is silver, not copper. Electrical resistivity of silver: 1,59.10-8 ohm.m Electrical resistivity of copper: 1,68.10-8 ohm.m A good electrical conductor has a very low electrical resistivity and a high electrical conductivity (the same principles for the thermal conductivity).
Copper is a good conductor, that's why it is used to make electrical wire.
Gold and Silver
Silver is the best electrical conductor. Copper is second. Gold is third. Aluminum is a good conductor but not for house wiring. It is used for high tension wires.
Metals.
Metals are indeed good conductors. Silver, which is a metal, is the best conductor.
A good example of electrical resistance is the heating element on a stove top it is a very poor conductor (high electrical resistance) because it is a poor conductor the electrical energy is converted to heat. Glass is one of the best insulators because its electrical resistance is so high it is a non conductor this lets us use it on high power lines to keep the electricity from coming in contact with the ground.
