Prata

Descrição:
Prata, com o símbolo químico Ag e o número CAS 7440-22-4, é um metal de transição conhecido por suas propriedades e aplicações distintas. Possui alta condutividade elétrica e térmica, tornando-se um excelente condutor, razão pela qual é amplamente utilizado em contatos e condutores elétricos. Prata é caracterizado por sua aparência metálica lustrosa e é altamente maleável e dúctil, permitindo que seja moldado em folhas finas ou estirado em fios. Quimicamente, Prata é relativamente inerte, resistindo à oxidação e corrosão, embora possa escurecer quando exposto a compostos de enxofre no ar. Forma vários compostos, incluindo nitrato de Prata e cloreto de Prata, e exibe propriedades antimicrobianas, tornando-o valioso em aplicações médicas. Prata também é utilizado em joias, fotografia e como investimento na forma de moedas e barras. Seus isótopos, particularmente Prata-107 e Prata-109, são estáveis, contribuindo para sua utilidade em várias aplicações científicas e industriais.
