Interesting Facts
- Heat capacity of Lithium is very high.
- Lithium inflammable and highly explosive metal, hence it has to be stored properly.
- Lanthanum metal is highly malleable, ductile and sectile.
- If exposed to air Lanthanum metal oxidizes rapidly.

Uses & Benefits
- The main usage of Lithium is manufacturing rechargeable batteries for electronic equipment and gadgets.
- it is also used in manufacturing non-rechargeable batteries.
- It has no commercial uses, but its alloys are in high demand. Lanthanum and Nickel alloy is used for the hydrogen gas storage.
- The best-known use for mischmetal alloy of Lanthanum is; as a ‘flints’ for cigarette lighters.
