O QUE SIGNIFICA ARSENIC EM INGLÊS
Arsênico
O arsênico é um elemento químico com o símbolo As e o número atômico 33. O arsênico ocorre em muitos minerais, geralmente em conjunto com enxofre e metais, e também como um cristal elementar puro. Foi documentado pela Albertus Magnus em 1250. O arsênico é um metalóide. Pode existir em vários alotrópicos, embora apenas a forma cinza tenha um uso importante na indústria. O principal uso do arsênico metálico é o fortalecimento de ligas de cobre e principalmente chumbo. O arsênico é um dopante comum de n-tipo em dispositivos eletrônicos semicondutores, e o composto optoeletrônico arsenieto de gálio é o semicondutor mais comum em uso após o silício dopado. O arsênico e seus compostos, especialmente o trióxido, são utilizados na produção de pesticidas, produtos de madeira tratada, herbicidas e inseticidas. Contudo, essas aplicações estão em declínio. O arsênico é notoriamente venenoso para a vida multicelular, embora algumas espécies de bactérias possam usar compostos de arsênico como metabolitos respiratórios. A contaminação por arsênico das águas subterrâneas é um problema que afeta milhões de pessoas em todo o mundo.
