Silber

Beschreibung:
Silber, mit dem chemischen Symbol Ag und der CAS-Nummer 7440-22-4, ist ein Übergangsmetall, das für seine besonderen Eigenschaften und Anwendungen bekannt ist. Es hat eine hohe elektrische und thermische Leitfähigkeit, was es zu einem ausgezeichneten Leiter macht, weshalb es weit verbreitet in elektrischen Kontakten und Leitern verwendet wird. Silber zeichnet sich durch sein glänzendes, metallisches Aussehen aus und ist hochgradig formbar und dehnbar, was es ermöglicht, in dünne Blätter geformt oder zu Drähten gezogen zu werden. Chemisch ist Silber relativ reaktionsträge, widersteht Oxidation und Korrosion, kann jedoch anlaufen, wenn es Schwefelverbindungen in der Luft ausgesetzt ist. Es bildet verschiedene Verbindungen, darunter Silber-Nitrat und Silber-Chlorid, und zeigt antimikrobielle Eigenschaften, was es in medizinischen Anwendungen wertvoll macht. Silber wird auch in Schmuck, Fotografie und als Investition in Form von Münzen und Barren verwendet. Seine Isotope, insbesondere Silber-107 und Silber-109, sind stabil und tragen zu seiner Nützlichkeit in verschiedenen wissenschaftlichen und industriellen Anwendungen bei.
