Vanadium was originally discovered by Andrés Manuel del RÃo (a Spanish-born Mexican mineralogist) in Mexico City, in 1801. He called it "brown lead" (now named vanadinite). Through experimentation, its colors reminded him of chromium, so he named the element panchromium. He later renamed this compound erythronium, since most of the salts turned red when heated. The French chemist Hippolyte Victor Collet-Descotils incorrectly declared that del Rio's new element was only impure chromium. Del Rio thought himself to be mistaken and accepted the statement of the French chemist that was also backed by Del Rio's friend Baron Alexander von Humboldt.
In 1831, Sefström of Sweden rediscovered vanadium in a new oxide he found while working with some iron ores and later that same year Friedrich Wöhler confirmed del Rio's earlier work. Later, George William Featherstonhaugh, one of the first US geologists, suggested that the element should be named "rionium" after Del Rio, but this never happened.
Metallic vanadium was isolated by Henry Enfield Roscoe in 1867, who reduced vanadium(III) chloride VCl3 with hydrogen. The name vanadium comes from Vanadis, a goddess in Scandinavian mythology, because the element has beautiful multicolored chemical compounds.

In 1803, Andres Manuel del Rio, a Spanish mineralogist working in Mexico City, first discovered a material he called “brown lead”. He later renamed this compound erythronium meaning red, a reference that this material turned red when heated. In 1831, a Swedish chemist named Nils Gabriel Sefstrom isolated a new material that he named vanadium in honor of the goddess of beauty and fertility, Vanadis. Ultimately, the name vanadium was chosen.

I'm not quite sure, but what I would do is find an older table of elements and look for it's number.
