O \u00edtrio \u00e9 um metal de transi\u00e7\u00e3o prateado-met\u00e1lico quimicamente semelhante aos lantan\u00eddeos e tem sido frequentemente classificado como um \u201celemento de terras raras\u201d.<\/span><\/p>\n<\/div>

Por causa de sua configura\u00e7\u00e3o eletr\u00f4nica de camada fechada, sua densidade e pontos de fus\u00e3o e ebuli\u00e7\u00e3o diferem significativamente da maioria dos outros lantan\u00eddeos.<\/span><\/p>\n<\/div>
