As an expert in the field of materials science, I can provide you with a comprehensive answer to your question regarding the best conductor of electricity. The metal that is considered the best conductor of electricity is silver. Silver has an electrical conductivity that is approximately 63% higher than that of copper, which is the next best conductor. This superior conductivity is due to the fact that silver has a single electron in its outer shell, which allows it to move freely and thus conduct electricity with minimal resistance.
However, despite its high conductivity, silver is not always the preferred choice for electrical applications. There are several reasons for this. First, silver is a relatively rare and expensive metal compared to copper. The cost of silver can be a prohibitive factor in many applications where large quantities of the metal are needed.
Second, while silver has the highest electrical conductivity, copper is often used as a substitute due to its lower cost and availability. Copper has a high conductivity that is only slightly less than that of silver, and it is much more abundant and affordable. This makes copper a more practical choice for many electrical applications, especially in the construction of electrical wires and cables.
Another metal that is used in electrical applications, particularly for high-quality connectors and contacts, is gold. Gold is known for its excellent corrosion resistance and does not tarnish or corrode easily, which makes it ideal for applications where long-term stability and reliability are important. Although gold's electrical conductivity is not as high as silver's, it is still very high and, combined with its other properties, makes it a preferred choice in certain high-end applications.
It is also worth noting that silver has other remarkable properties. It has the highest thermal conductivity of any element, which makes it useful in applications where heat transfer is critical. Additionally, silver has the highest light reflectance, which is why it is often used in mirrors and other reflective surfaces.
In summary, while silver is the best conductor of electricity, its use in electrical applications is often limited by its cost and availability. Copper and gold are more commonly used due to their balance of conductivity, cost, and other beneficial properties.

Silver also has the highest thermal conductivity of any element and the highest light reflectance. Although it is the best conductor, copper and gold are used more often in electrical applications because copper is less expensive and gold has a much higher corrosion resistance.
