CAS 7439-92-1

Chumbo

Descrição:

Chumbo, com o número CAS 7439-92-1, é um metal pesado classificado como um metal pós-transição. É conhecido por sua maleabilidade, ductilidade e baixo ponto de fusão, o que permite que seja facilmente moldado e formado. Chumbo tem uma cor branco-azulada quando cortado fresco, mas se oxida para um cinza opaco ao ser exposto ao ar devido à formação de uma camada de óxido. É relativamente denso, com um alto peso atômico, e apresenta baixa condutividade elétrica em comparação com outros metais. Chumbo também é conhecido por sua resistência à corrosão, tornando-o útil em várias aplicações, incluindo baterias, blindagem contra radiação e materiais de soldagem. No entanto, Chumbo é altamente tóxico, especialmente para o sistema nervoso, e pode causar sérios problemas de saúde quando exposto, levando a regulamentos rigorosos sobre seu uso e descarte. Em termos de comportamento químico, Chumbo pode formar vários compostos, incluindo óxidos, sulfetos e haletos, e normalmente apresenta um estado de oxidação +2 na maioria de seus compostos.
