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