CAS 7440-02-0: Níquel

Descrição: Níquel é um metal de transição com o símbolo químico Ni e o número CAS 7440-02-0. É caracterizado por sua aparência prateada e é conhecido por sua alta ductilidade e maleabilidade. Níquel tem um ponto de fusão e um ponto de ebulição relativamente altos em comparação com muitos outros metais, tornando-o adequado para aplicações em altas temperaturas. Apresenta excelente resistência à corrosão, particularmente em ambientes alcalinos, razão pela qual é frequentemente utilizado em ligas e revestimentos para aumentar a durabilidade. Níquel é ferromagnético à temperatura ambiente, o que significa que pode ser magnetizado. Em termos de reatividade química, Níquel pode formar vários estados de oxidação, sendo +2 o mais comum em compostos. Reage prontamente com ácidos, liberando gás hidrogênio, e também pode formar íons complexos em solução. Níquel é um elemento traço essencial em sistemas biológicos, desempenhando um papel em certos processos enzimáticos, mas a exposição excessiva pode ser tóxica. Suas aplicações variam desde a produção de aço inoxidável até baterias e catalisadores em reações químicas.
