عن Silver
Silver is a soft, white, lustrous transition metal with the highest electrical conductivity of any element, and the highest thermal conductivity and reflectivity of any metal. It has been a precious metal for thousands of years and is naturally antimicrobial.
Uses & Applications
Jewelry, silverware, coins, photography, electronics, solar panels, water purification, and medical dressings.
حقيقة مضحكة
Silver has the highest electrical conductivity of any element, even higher than copper, but its cost prevents standard wiring use.
