Interesting Facts
- IUPAC allotted a temporary name to Dubnium metal as “ Unnilpentium”.
- In the production of Dubnium, thermal gradient chromatography is used.
- Thorium metal is used as an alternate option over Uranium for nuclear fuel.
- Thorium metals appearance (silvery white, soft) is somewhat similar to Lead metal.
