Metals are well known as great conductors of electricity because they contain free mobile electrons.
Materials possessing movable electrically charged, known as "electrons" in metals, are electric conductors. Electrons migrate when an electric load is connected to metal at specific places, allowing electric current to pass through.
Electricity must be able to flow electrons through a substance to make it a good conductor; the more free ions in a metal, the better its conductivity.
Once you are aware of ‘ Why do metals conduct electricity. You are not done. You need to know more facts about metal and electricity. Following are your guide.
Conductivity of Electricity
Metals conduct electricity due to metallic bonding. A constantly moving "sea of electrons" surrounds the metal atoms in a metallic connection. The metal may conduct electricity and travel freely among the ions because of this moving stream of electrons.
To some extent, all metals carry electricity. Some metals have electricity better than others. Electric conductors include copper, silver, aluminum, gold, steel, and brass. Silver, gold, and copper are the most conductive metals.
Metals in their Conductive Order
Alloys and pure elements are included in this table of electric conductivity. The list implies that all specimens are the same size because the size and form affect their conductivity. Metal Detecting World has provided the fundamental kinds of material and some typical alloys in a sequence of decreasing conductive connection.

With so many metals conducting electricity, the answer to the question, ‘ do metals conduct electricity. Will always be yes.
Conductivity of Silver
"Because it has a higher number of moveable atoms, silver is the finest conductor of electricity" (free electrons). Electricity must be able to flow electrons through a substance to make it a good conductor; the more free electron in a metal, the better its conductivity. On the other hand, Silver is more costly than other metals and is only utilized for specialized equipment such as satellites or circuit boards.
Copper Conductivity is a property of copper.
"Copper is less receptive than Silver, but it is less expensive and is widely employed in household equipment as an effective conductor. The majority of wires are copper-plated, and the cores of electromagnets are usually coated with copper wire. Copper is also simple to solder & wrap in wires, so it's frequently employed when many current collectors are needed.
Conductivity of Gold
While gold is an excellent electrical conductor and does not tarnish when exposed to air, it is prohibitively expensive for everyday use. Its unique qualities make it useful for a variety of applications.
Conductivity of Aluminum
Aluminum can conduct electricity, but not as well as copper. Aluminum generates an electrically resistive oxide surface in electrical connections, leading the contact to overheat. Aluminum is used in high-voltage transmission lines that are enclosed in steel for added protection.
Electrical Conductivity Affecting Factors
A variety of factors influences the ability of a substance to conduct electricity. Here's how ThoughtCo discusses these factors:
Temperature changes the conductivity of Silver or another conductor. In general, raising the temperature promotes thermal stimulation of the atoms, which lowers conductivity while increasing it.
