2 Facts
2.1 Interesting Facts
- IUPAC allotted a temporary name to Dubnium metal as “ Unnilpentium”.
- In the production of Dubnium, thermal gradient chromatography is used.
- Vanadium is a highly reactive metal, hence it is not found free in nature.
- Vanadium can be found in almost 65 different types of minerals.
