Can gold and silver conduct electricity?
Of all metals, silver has the best conductivity. At room temperature, the resistivity of silver is only (25 degrees) 1.6 1. The conductivity of gold is second only to silver and copper, and the conductivity of silver is 76.7%, ranking third. The resistivity of gold is (25 degrees) 2.42.
The conductivity of a solid refers to the long-distance migration of electrons or ions in the solid under the action of an electric field, which is usually dominated by a kind of charge carriers, such as: electron conductors, with electron carriers as the main body; Ionic conductivity based on ionic carriers;
Mixed conductors have both carriers and ions. In addition, some electrical phenomena are not caused by carrier migration, but by solid polarization induced by electric field, such as dielectric phenomena and dielectric materials.

The difference between metals and nonmetals: From the chemical point of view, metals are connected by metal bonds, while nonmetals are connected by ionic bonds or valence bonds. Physically, metals generally have electrical conductivity, thermal conductivity, ductility and metallic luster, and most of them are solid, only mercury is liquid at room temperature.
Most nonmetals are insulators, and only a few nonmetals are conductors (carbon) or semiconductors (silicon). However, due to the rapid development of science and technology, the differences between them are becoming less and less obvious. The development of nanotechnology makes the difference between metal and nonmetal smaller and smaller.
