Which metal is the best conductor of electricity class10?

Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons) owing to the fact that gold has a preceding f-orbital from the actinide series.

Which metal is the best conductor of electricity?

Which Metal Conducts Electricity The Best?

Material IACS (International Annealed Copper Standard)
Ranking Metal % Conductivity*
1 Silver (Pure) 105%
2 Copper 100%
3 Gold (Pure) 70%

Which material is the best conductor Class 10?

Silver has the lowest resistivity. Hence, silver is the best conductor.

Which of the following is best conductor of electricity?

Silver is the best conductor of electricity.

Why is silver the best conductor?

A conductor is a material which gives very little resistance to the flow of an electric current or thermal energy. … Silver is the best conductor because its electrons are freer to move than those of the other elements, thereby making it more suitable for the conduction of electricity and heat than any other element.

Is Aluminium good conductor of electricity?

Aluminum. Aluminum is yet another metal known for its high conductivity of electricity. Though by volume its conductivity is only 60% of copper, by weight, one pound of aluminum has the electrical current-carrying capacity of two pounds of copper. … Aluminum is often used in satellite dishes.

Is graphite a good conductor of electricity?

In a graphite molecule, one valence electron of each carbon atom remains free. Due to the free electrons in its framework, graphite can perform electricity. Therefore, graphite is said to be a good conductor of electricity.

Is Mercury a good conductor of electricity?

Mercury is the only metal that is liquid at standard conditions for temperature and pressure. Mercury is a poor conductor of heat, but a fair conductor of electricity. … Mercury dissolves to form amalgams with gold, zinc, and many other metals.

What metal is the best conductor of electricity gold or silver?

The most electrically conductive element is silver, followed by copper and gold. Silver also has the highest thermal conductivity of any element and the highest light reflectance.

Which is better conductor silver or copper?

Silver, a precious metal, is the only metal with a higher electrical conductivity than copper. The electrical conductivity of silver is 106% of that of annealed copper on the IACS scale, and the electrical resistivity of silver = 15.9 nΩ•m at 20°C.

Which is best conductor of electricity gold or silver?

Gold conducts heat and electricity.

Copper and silver are the best conductors, but gold connections outlast both of them because they do not tarnish.
