There are different types of conductivity, including electrical, thermal, and acoustical conductivity. The most electrically conductive element is silver, followed by copper and gold.
Silver is the best conductor of electricity but copper is used instead of silver for making wires.
As a result, silver is by far the most conductive metal on Earth. This is because silver only has one valence electron. In addition, this single electron is free to move around with little resistance.
In general, metals have good electrical conductance due to the arrangement of electrons in their atoms. The precious metals, gold, and silver are no exception, with silver having the highest conductance. Although gold is a good conductor, its usefulness in electrical equipment is due to its chemical stability.
Which metal is the best and poorest conductor of electricity?
Silver is a poor conductor of electricity while mercury is a very good conductor.
Therefore, Tungsten is the poorest conductor of electricity.
The electrical conductivity of copper is slightly higher at 5.96 x107 S/m than gold which is 4.11×107 S/m. More importantly is the lifespan of the two metals. Copper has a high oxidation level.

Electrical Conductivity
Aluminium is a good conductor of electricity, whereas Stainless steel is a poor conductor. Due to its high conductivity, lightweight and corrosion resistance, high voltage overhead powerlines are generally made of aluminium.
Hence, silver metal is the best conductor of heat and electricity.
Among the metals given above, Tungsten evidently has the highest resistance and therefore is the poorest conductor of electricity. It can be inferred from the fact that due to its high resistance it gets heated up and thus is used as filament in incandescent bulbs.
Therefore, Copper is the second-best conductor of heat.
Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood.
From the given options, Silver has the highest electrical conductivity, and Aluminum has the least. On a scale of 0 to 100 for electrical conductivity, silver ranks 100, with copper at 97 and gold at 76, aluminum at 60.
What is the name of the very promising conductive material?
Polyaniline. Polyaniline is one of the most promising conductive polymers and, therefore, one of the most studied ones.
- coal, which produces 44.9 % of all power in the U.S. Along with water, coal was used in the first power plants, and it remains the cheapest known raw material used to produce electricity. ...
- natural gas, which accounts for 23.4% of the country's total power.
This is because metals have lots of free electrons and promote mobility. Some of the best metal conductors are Silver (Ag), Copper (Cu) and Gold (Au). The more free electrons present in a metal, the greater its conductivity. Comparatively, silver has better electrical conductivity than copper and gold.
Diamond does not conduct electricity.
Though silver is a very good conductor of electricity but still that is not used in electric wiring primarily due to its cost. It's very expensive compared to the widely used wiring material copper. Another reason for not using silver is that , it oxidizes easily and tarnishes when it comes in contact with air.

- Pure silver is the finest conductor of electricity.
- Yet unsurprisingly, it is not one of the metals that are used to carry electricity most frequently.
- There are a few disadvantages to the widespread usage of pure silver.
Gold has played an important role in the electronics sector for decades. It does not corrode or tarnish, unlike other highly conductive metals, such as copper and silver. And it is a soft, pliable material, which can be easily drawn out into narrow wires or plated into thin coatings.
Diamond is actually a much better heat conductor than silver, around 5 times better for an average diamond. Scientists have also made super pure diamonds that can easily be up to 5 times better than regular diamonds.
Yes, graphene is more conductive than silver when graphene is at room temperature. This is because graphene possesses better conductivity compared to silver at room temperature. Thus, materials are more conductive than silver when subjected to precise conditions. Graphene is also a two-dimensional conductor.

Does gold stick to magnet?
If it's real gold it will not stick to the magnet. (Fun fact: Real gold is not magnetic.) Fake gold, on the other hand, will stick to the magnet. If that necklace leaps to the magnet, your significant other has some explaining to do.
Silver has the highest electrical conductivity of all metals. In fact, silver defines conductivity - all other metals are compared against it. On a scale of 0 to 100, silver ranks 100, with copper at 97 and gold at 76.
As copper is an excellent conductor of heat, it's good for heat exchangers, heat sinks, and even saucepan bottoms. Because steel is a poor conductor of heat, it's good for high-temperature environments like airplane engines.
Metals are good conductors of electricity because of the presence of free electrons which act as charge carriers. Silver is a metal so it is a good conductor of electricity.
Gold is used as a contact metal in the electronics industry as it is a good conductor of both electricity and heat.
As Tungsten is a metal, it is a good conductor of electricity. Also it is very hard and has very high melting point. Because of its high thermal stability and good conductivity properties it has many uses in electronic devices. It is also used as filaments in bulbs and vacuum tubes.
The data suggests that Copper is the best conductor of heat and Stainless Steel the worst. Based on the data I collected from my experiments, Copper was the best conductor, Aluminum the 2nd, Brass the 3rd, Lead the 4th and Stainless Steel the worst.
Aluminium is a good conductor but not best. Silver is the best conductor. Silver has approx 6 % more conductivity than copper. Aluminium has less conductivity than both But due to low density, low cost and high resistance to corrosion Aluminium is preferred.
Silver is the best conductor of electricity. Despite silver's immense ability to conduct electricity, it is often not used in wiring. The reason is silver is exponentially more expensive than the other option, copper.

Why is gold not used for electrical wires?
Gold is not used for making electric wires because it is too rare, and too costlier than Copper. Silver and copper are used for making wires.
Copper, silver, aluminum, gold, steel, and brass are common conductors of electricity. The most highly conductive metals are silver, copper, and gold.
There are four types of conductors, namely, good conductors, semiconductors, resistors and non-conductors. Non-conductors are also termed as insulators.
- silver.
- copper.
- gold.
- aluminum.
- iron.
- steel.
- brass.
- bronze.
Therefore, Tungsten is the poorest conductor of electricity.
As a result, silver is by far the most conductive metal on Earth. This is because silver only has one valence electron. In addition, this single electron is free to move around with little resistance. As a result, metals like silver and copper are a few of the metals with this particular characteristic.
Materials that are poor conductors of electricity are called insulators. Some examples are wood, glass, plastics, non-metal elements that are polymers of hydrocarbons.
Another common misconception is that pure Gold is the best conductor of electricity. While Gold does have a relatively high conductive rating, it is actually less conductive than Copper.
Since each carbon atom is attached to the other four carbon atoms through strong covalent bonds. Hence, no free electrons are present in the diamond crystal. Due to the absence of free electrons, diamond is a poor electrical conductor.
Plastic, wood, glass and rubber are good electrical insulators. That is why they are used to cover materials that carry electricity. The plastic covering that surrounds wires is an electrical insulator. It stops you from getting an electrical shock.
What is the most electrically conductive material and why?
Silver: it is considered the best conductor of electricity, though it is often only used in specific cases due to its high cost.
In fact, silver defines conductivity - all other metals are compared against it. On a scale of 0 to 100, silver ranks 100, with copper at 97 and gold at 76.
