Fun with vanadium oxides
Vanadium, the transition metal at number 23 on the periodic table, is one of those elements that sounds more like something out of a superhero movie than a real substance. You might expect that vanadium oxide would be of vanishingly small interest, but the reality is different. I should really have said the vanadium oxides, because thanks to vanadium’s five valence electrons there are enough oxides to sound like a successful Hollywood franchise – vanadium (II) oxide, VO, vanadium (III) oxide, V2O3, vanadium (IV) oxide, VO2 and vanadium (V) oxide, V2O5, without going into extra intermediate phases that can produce entertaining combos like V6O13 and V8O15.
Also like those Hollywood franchises, some instalments are more interesting than others, as you'll discover by taking a listen...
