Oro

Descripción:
Oro, con el número de registro del Chemical Abstracts Service (CAS) 7440-57-5, es un elemento metálico muy valorado conocido por su distintivo color amarillo y brillo. Se clasifica como un metal de transición y está representado por el símbolo Au en la tabla periódica. Oro se caracteriza por su excelente maleabilidad y ductilidad, lo que le permite ser fácilmente moldeado en láminas delgadas o estirado en hilos sin romperse. También es altamente resistente a la corrosión y oxidación, lo que lo hace estable en diversos entornos. Oro tiene una alta densidad y es un buen conductor de electricidad y calor. Químicamente, es relativamente inerte, reaccionando solo con algunas sustancias, como halógenos y cianuros, bajo condiciones específicas. Oro se encuentra a menudo en la naturaleza en su forma nativa, típicamente en depósitos aluviales, y se utiliza comúnmente en joyería, electrónica y como estándar para sistemas monetarios debido a su valor intrínseco y rareza. Sus propiedades únicas y atractivo estético lo han convertido en un símbolo de riqueza y prestigio a lo largo de la historia.
