ETIMOLOGIA CUVÂNTULUI VANADIUM
New Latin, from Old Norse Vanadis, epithet of the goddess Freya + -ium.
CE ÎNSEAMNĂ VANADIUM ÎN ENGLEZĂ?
vanadiu
Vanadiul este un element chimic cu simbolul V și numărul atomic 23. Acesta este un metal de tranziție durificat, dur, argintiu, ductil și maleabil. Elementul se găsește numai în formă combinată chimic în natură, dar, odată izolat artificial, formarea unui strat de oxid stabilizează metalul liber într-o oarecare măsură împotriva oxidării ulterioare. Andrés Manuel del Río a descoperit compuși de vanadiu în 1801 în Mexic, analizând un mineral nou purtat pe bază de plumb, pe care el la numit "plumb maro", și a presupus că calitățile sale se datorează prezenței unui element nou pe care el la numit eritroniu, majoritatea sărurilor sale s-au transformat de la culoarea lor inițială la roșu. Patru ani mai tarziu, cu toate acestea, el a fost convins de alti oameni de stiinta ca eritronul a fost identic cu cromul. Clorurile de vanadiu au fost generate în 1830 de Nils Gabriel Sefström, care astfel au demonstrat că a fost implicat un element nou pe care la denumit "vanadiu" după zeița scandinavă a frumuseții și fertilității, Vanad. Ambele nume au fost atribuite gamei largi de culori găsite în compușii de vanadiu. Del Rio minerala de plumb a fost mai târziu redenumit vanadinite pentru conținutul său de vanadiu.
