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.
