Found by: Sef Staum

Year of discovery: 1830
The element vanadium was first discovered by Mexican mineralogist Celelieva in 1801 in a lead specimen containing vanadium. Because the salt solution of this new element appears bright red when heated, it was named "Eletroni", which means "red". But at the time, it was thought that it was the contaminated element chromium, so it was not recognized. Later, in 1830, he wrote that the Buddhist temple Telemu discovered it in iron extracted from Swedish iron ore and affirmed that it was a new element called vanadium.
