Ouro

Descrição:
Ouro, com o número de registro do Chemical Abstracts Service (CAS) 7440-57-5, é um elemento metálico altamente valorizado conhecido por sua distinta cor amarela e brilho. É classificado como um metal de transição e é representado pelo símbolo Au na tabela periódica. Ouro é caracterizado por sua excelente maleabilidade e ductilidade, permitindo que seja facilmente moldado em folhas finas ou estirado em fios sem quebrar. Também é altamente resistente à corrosão e oxidação, tornando-o estável em vários ambientes. Ouro tem uma alta densidade e é um bom condutor de eletricidade e calor. Quimicamente, é relativamente inerte, reagindo apenas com algumas substâncias, como halogênios e cianetos, sob condições específicas. Ouro é frequentemente encontrado na natureza em sua forma nativa, tipicamente em depósitos aluviais, e é comumente usado em joias, eletrônicos e como padrão para sistemas monetários devido ao seu valor intrínseco e raridade. Suas propriedades únicas e apelo estético o tornaram um símbolo de riqueza e prestígio ao longo da história.
