'''Sølv''' er et [[grundstof]] med [[atomtegn]]et '''Ag''' (fra [[Latin]] ''{{lang|la|argentum}}'', fra [[proto-indoeuropæisk]] ''h₂erǵ'': "skinnende" eller "hvid") og [[atomnummer]]et 47. Det er et blødt, hvidt, skinnende [[overgangsmetal]], med meget høj [[Specifik ledningsevne|elektrisk ledningsevne]], [[Specifik varmeledningsevne|varmeledningsevne]] og [[reflektion]]sevne for et [[metal]]. Metallet findes i [[Jordens skorpe]] i sin rene, frie stofform, og som en [[legering]] med [[guld]] og andre metaller, samt i mineraler såsom [[argentit]] og [[chlorargyrit]]. Det meste sølv fremstilles som et biprodukt ved [[raffinering]] af [[kobber]], guld, [[bly]] og [[zink]].

'''Silver''' is a [[chemical element]] with the [[Symbol (chemistry)|symbol]] '''Ag''' (from the [[Latin]] ''{{lang|la|argentum}}'', derived from the [[Proto-Indo-European]] [[wikt:Reconstruction:Proto-Indo-European/h₂erǵ-|''h₂erǵ'']]: "shiny" or "white") and [[atomic number]] 47. A soft, white, lustrous [[transition metal]], it exhibits the highest [[electrical conductivity]], [[thermal conductivity]], and [[reflectivity]] of any [[metal]].{{citation needed|date=November 2020}} The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an [[alloy]] with [[gold]] and other metals, and in minerals such as [[argentite]] and [[chlorargyrite]]. Most silver is produced as a byproduct of [[copper]], gold, [[lead]], and [[zinc]] [[refining]].

Other than in [[currency]] and as an [[investment]] medium ([[coins]] and [[bullion]]), silver is used in [[solar panels]], [[water filtration]], [[jewellery]], ornaments, high-value tableware and utensils (hence the term "[[Silver (household)|silverware]]"), in [[electrical contact]]s and [[Electrical conductor|conductors]], in specialized mirrors, window coatings, in [[catalysis]] of chemical reactions, as a colorant in [[stained glass]] and in specialised confectionery. Its compounds are used in [[photographic film|photographic]] and [[X-ray]] film. Dilute solutions of [[silver nitrate]] and other silver compounds are used as [[disinfectant]]s and microbiocides ([[oligodynamic effect]]), added to [[bandage]]s and wound-dressings, [[catheter]]s, and other [[medical instrument]]s.
