ETIMOLOGIA DA PALAVRA VANADIUM
New Latin, from Old Norse Vanadis, epithet of the goddess Freya + -ium.
O QUE SIGNIFICA VANADIUM EM INGLÊS
Vanádio
O vanádio é um elemento químico com o símbolo V e o número atômico 23. É um metal de transição resistente, cinza prateado, dúctil e maleável. O elemento é encontrado apenas na forma quimicamente combinada na natureza, mas uma vez isolada artificialmente, a formação de uma camada de óxido estabiliza o metal livre um pouco contra a oxidação adicional. Andrés Manuel del Río descobriu compostos de vanádio em 1801 no México, analisando um novo mineral de chumbo chamado "chumbo marrom", e presumiu que suas qualidades se deveriam à presença de um novo elemento, que ele chamou de erythronium, pois, ao aquecer, A maioria dos seus sais passou da cor inicial para o vermelho. Quatro anos depois, no entanto, ele foi convencido por outros cientistas de que o erythronium era idêntico ao crómio. Os cloretos de vanádio foram gerados em 1830 por Nils Gabriel Sefström, que provou que um novo elemento estava envolvido, o qual ele chamou de "vanádio" depois da deusa escandinava de beleza e fertilidade, Vanadís. Ambos os nomes foram atribuídos à ampla gama de cores encontradas nos compostos de vanádio. O mineral de chumbo de Del Rio foi mais tarde renomeado vanadinita pelo seu conteúdo de vanádio.
