3 Facts
3.1 Interesting Facts
- IUPAC allotted a temporary name to Dubnium metal as “ Unnilpentium”.
- In the production of Dubnium, thermal gradient chromatography is used.
- Heat capacity of Lithium is very high.
- Lithium inflammable and highly explosive metal, hence it has to be stored properly.
