:Estrôncio
Descrição:
Estrôncio é um elemento químico com o símbolo Sr e número atômico 38. É um metal alcalino-terroso macio e de cor branco-prateado que é altamente reativo, especialmente com água e ar, formando uma camada de óxido protetora. Estrôncio é tipicamente encontrado na natureza em formas minerais, como celestina e estrontianita. Tem um ponto de fusão e um ponto de ebulição relativamente baixos em comparação com muitos outros metais. Estrôncio é conhecido por sua chama vermelha brilhante quando queimado, tornando-o útil em pirotecnia e fogos de artifício. Em termos de importância biológica, Estrôncio é semelhante ao cálcio e pode ser incorporado aos ossos, o que tem implicações tanto para a saúde quanto para estudos ambientais. Compostos de Estrôncio, como carbonato de Estrôncio e sulfato de Estrôncio, são usados em várias aplicações, incluindo na produção de ímãs de ferrite e no campo médico para certos tratamentos. Devido à sua reatividade, Estrôncio deve ser manuseado com cuidado, geralmente armazenado sob óleo ou em uma atmosfera inerte para evitar oxidação.
