ETIMOLOGIA DELLA PAROLA VANADIUM
New Latin, from Old Norse Vanadis, epithet of the goddess Freya + -ium.
CHE SIGNIFICA VANADIUM IN INGLESE
Vanadio
Il vanadio è un elemento chimico con il simbolo V ed il numero atomico 23. È un metallo di transizione duro e argilloso grigio, duttile e malleabile. L'elemento è trovato solo in forma chimica combinata in natura, ma una volta isolata artificialmente, la formazione di uno strato di ossido stabilizza il metallo libero in qualche modo contro ulteriore ossidazione. Andrés Manuel del Río ha scoperto composti di vanadio nel Messico nel 1801, analizzando un nuovo minerale di piombo chiamato "piombo marrone" e presumibilmente le sue qualità erano dovute alla presenza di un nuovo elemento che egli chiamò eritronio, La maggior parte dei suoi sali si è trasformata dal colore iniziale al rosso. Quattro anni dopo, tuttavia, fu convinto da altri scienziati che l'eritronio era identico al cromo. I cloruri di vanadio furono generati nel 1830 da Nils Gabriel Sefström, che dimostrò perciò che un nuovo elemento era coinvolto, chiamato "vanadio" dopo la dea scandinava di bellezza e fertilità, Vanadís. Entrambi i nomi sono stati attribuiti all'ampia gamma di colori presenti nei composti vanadio. Il minerale piombo di Del Rio è stato successivamente rinominato vanadinite per il suo contenuto di vanadio.
