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.
- Heat capacity of Lithium is very high.
- Lithium inflammable and highly explosive metal, hence it has to be stored properly.
