Gold is a very good conductor of electricity. It is often used as plating for connectors because it does not tarnish or corrode easily. Even though copper and silver are better conductors than gold, gold retains its conductivity longest because it does not tarnish or corrode easily. For this reason, gold is most often used in plating where it is exposed to the air.

Is copper a good conductor of electricity? It is due to the availablity of free electrons. All metals such as Copper can be considered as atomic nuclei surrounded by a sea of electrons which are free to move around … with little resistance, which makes all metals good conductors of electricity (and heat, incidentally).

What element is the best electrical conductor? Report Abuse. The best electrical conductor are superconductors. But it is not an element. Among other metals Aluminium,copper,gold ,platinum,silver etc ar very good conductors. But to use gold, silver and platinum is not at all economic.he best conductor is silver. Then Copper Here is a list of specific resistance in Ohms*mm^2/m-Silver - 0.016 - Copper - 0.0175 - Gold - 0.022 - Aluminium 0.0278 Those are the best conductors according their rank. There are non-metallic conductors.

Copper: the essentials It is malleable, ductile, and a good conductor of heat and electricity (second only to silver in electrical conductivity). Its alloys, brass and bronze, are very important. Monel and gun metals also contain copper.

Conductors and Insulators Obviously, string is an insulator, and copper is a conductor. As a general rule, substances which are good conductors of heat are also good conductors of electricity. Thus, all metals are conductors, whereas air, (pure) water, plastics, glasses, a...

Electrical conductivity The electrical conductivity of a metal (or its reciprocal, electrical resistivity) is determined by the ease of movement of electrons past the atoms under the influence of an electric field. This movement is particularly easy in copper, silver, gold, and aluminum—all of which are well-known conductors of electricity.

- Metals are a good conductor of heat and electricity because of their bonding. Metallic bonding consists of a sea of electrons rather than discreet bonds. The free electrons ar … e able to move very freely. Since electricity and heat need electrons to move, the bonding promotes conductivity.

What are some good conductors of thermal energy? Generally good conductors of heat are also good conductors of electricity. Good conductors are commonly understood to be aluminum, copper, silver, and gold; with a trade being made for higher price as conductance increases. Note that all of these materials are solids. Thermodynamic conductance is that ability of a material to allow heat to flow through it.

Example of good conductor of electricity? Best Answer: Any material that conducts heat or electricity (as opposed to an insulator, or nonconductor). A good conductor has a high electrical or heat conductivity, and is generally a substance rich in loosely-held free electrons, such as a metal.Copper and aluminum are good conductors.A poor conductor (such as the non-metals glass, porcelain, and rubber) has few free electrons and resists the flow of electricity or heat. Carbon is exceptional in being non-metallic and yet (in some of its forms) a relatively good conductor of heat and electricity.Substances such as silicon and germanium, with intermediate electrical conductivities that are improved by heat, light, or impurities, are known as semiconductors.arbon is exceptional in being non-metallic and yet (in some of its forms) a relatively good conductor of heat and electricity.

Conductors and Insulators Conductors and Insulators. In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. Conductor implies that the outer electrons of the atoms are loosely bound and free to move through the material.

Why are tin and lead good conductors of electricity? give reference to their structure? Report Abuse. Tin is actualy a bad conducter. Lead is good because it has a sea of free electrons which are free to move around it. Electrons are pushes to move around the circuit, so if electricity which is a voltage of electrons goes through a metal which has this, it'l do the trick. Shane A · 7 years ago.

- Copper is a good conductor of electricity because the valence electrons are free and repel each other so strongly that it causes the repulsion of other electrons. This essentially forces the electricity down the piece of copper, or conducts it down the metal. Continue Reading.

What Is the Most Conductive Element? As to why silver is the best conductor, the answer is that its electrons are freer to move than those of the other elements. This has to do with its valence and crystal structure. Most metals conduct electricity. Other elements with high electrical conductivity, are aluminum, zinc, nickel, iron and platinum. Brass and bronze are electrically conductive alloys, rather than elements.

- Pure iron is the best conductor of electricity in the current  world. It transmits up to eight million electrons per minute  through a gauge of 10mm. Pure iron can conduct e…lectricity better  than copper and can harvest electricity, although it would have to  have added allotropes for that to happen.

Which material is very good conductor of heat but bad conductor of electricity? Rubber is a good conductor if heat but a bad conductor if electricity. Diamond will do the first two IIRC, but its intrinsic strength is much higher than stainless steel. However its failure modes are very different, so comparing the two is a bit thankless.... mika.

- Most metals are good conductors of heat, silver and copper being best, which is why Revere Ware was famous for their copper bottomed pots. Among non-metals, helium is a remarkably good conductor of heat, since the atoms are so small and fast.

Which Would Be the Best Insulator: Diamond, Gold, Lead or Concrete? Two of these substances are electrical conductors and two are insulators. Gold and lead, being metals, make poor insulators. Diamonds and concrete are nonmetallic and have good insulating properties, but diamond would make the better insulator, due to its strong resistivity.

- For instance diamond is a good conductor of light, is a conductor of heat but is still a good electrical insulator. A conductor is something that allows electricity, heat or light to flow through it. Most metals are conductors of heat and electricity.
