Silver is a chemical element with the symbol Ag (derived from the Latin argentum) and atomic number 47, classified as a soft, white, lustrous transition metal that exhibits the highest electrical and thermal conductivity of any element.

As for the metal itself, silver is the element with the highest level of reflectivity. 95% of the light reaching a mirrored silver surface bounces back. Aluminum is the next most reflective at only 90% so silver wins handily.

Not surprisingly, it is the metal of choice with which to make mirrors. However, silver is a delicate metal. On top of being soft it is reactive with sulfur traces of which are suspended in air. Thus, over time silver dulls and its surface will become completely black unless polished or treated with chemicals.

Native silver, the naturally occurring metallic form of the element, has a Mohs hardness of 2.5–3, hackly fracture, and no cleavage. It commonly occurs in wire-like, dendritic, arborescent, massive, or capillary aggregates; well-formed cubic, octahedral, or dodecahedral crystals are rare and often distorted or twinned.

Silver possesses the highest electrical conductivity of any metal, measured at 6.30 × 10 S/m at 20°C. This exceptional property stems from the free electron model, wherein valence electrons behave as a nearly free gas within the delocalized conduction band, facilitated by silver’s filled d-band that lies below the Fermi level and minimizes electron scattering.

Similarly, its thermal conductivity ranks among the highest for metals at 429 W/(m·K), also attributable to efficient phonon and electron transport in this band structure.

The electrical resistivity of silver, the inverse of conductivity, is 1.59 × 10⁻⁸ Ω·m at 20°C and increases with temperature due to enhanced electron-phonon scattering, reducing conductivity as thermal vibrations intensify.

Compared to other metals, silver surpasses copper’s electrical conductivity of approximately 5.96 × 10 S/m while offering greater thermal stability than gold (4.10 × 10 S/m electrical, 318 W/(m·K) thermal); however, its higher cost relative to copper limits widespread industrial adoption for conduction applications.
