Vanadium group: olive-green tarnished |v| chunks, |nb| chunks, and |ta| chunks
The Vanadium metal group: |v|, |nb|, and |ta|
One small, two medium, and one large sample of Niobium metal chunks. The large chunk shows some oxidation.
Roughly 3.5 cm diameter chunk of Niobium metal, shaped somewhere between disc and a sphere.
Beautiful small crystal of Niobium metal. |nb| is a transition metal and should not be confused with the rare-earth metal |nd|!
