Interesting Facts
- Cerium is a rare earth metal but still it is not rare at all.
- It’s non-toxic compound Cerium sulfide has a rich red color and it is used as a pigment.
- Cerium metal is also used in Flat screen TVs, light bulb, floodlights, etc.
- IUPAC allotted a temporary name to Dubnium metal as “ Unnilpentium”.
- In the production of Dubnium, thermal gradient chromatography is used.
