Silver (Ag)
Silver is a soft, white, lustrous transition metal possessing the highest electrical conductivity of any element.
Core Principles & Analysis
- Silver has been mined and worked since antiquity, with extraction from lead ores in Anatolia dating back roughly 5,000 years.
- It has the highest electrical conductivity, thermal conductivity, and visible-light reflectivity of any metal.
- Silver is used in electronics, solar photovoltaic cells, brazing alloys, and antimicrobial wound dressings, and it once underpinned film photography.
