ezüst

Ezüst, the Hungarian name for the chemical element known as silver in English, has the symbol Ag and atomic number 47. It is a bright, white metal that is soft, malleable and ductile, and it is among the best electrical and thermal conductors. It is also highly reflective, giving it the characteristic luster of polished metal.

Occurrence and production: Native silver occurs rarely; more commonly it is found in ores such as argentite (silver sulfide) and chlorargyrite (horn silver). It is typically obtained as a byproduct of mining for copper, lead, and zinc. World production is dominated by a few countries, including Mexico, Peru, China, Russia and Australia, with refining and electrochemical processes used to separate silver from other metals.

Uses and applications: Silver is used in jewelry, coins, utensils and various decorative objects. It is a critical material in electronics for electrical contacts and conductors, in photovoltaics, and as a catalyst in chemical reactions. Historically, silver halides were used in photographic film. Silver also has antimicrobial properties and is used in some medical devices and coatings.

Properties and safety: Silver melts at 962 degrees Celsius and boils at about 2162 °C. It is relatively inert but silver compounds can be toxic and prolonged exposure can cause argyria, a condition causing blue-gray skin discoloration. Environmental releases are managed to minimize impact.
