Interesting Facts
- Original name of Technetium was Masurium.
- At the time of its discovery it found in sample of Molybdenum.
- Lanthanum metal is highly malleable, ductile and sectile.
- If exposed to air Lanthanum metal oxidizes rapidly.

Uses & Benefits
- Technetium is a radioactive metal and hence it is used for medical studies and other research purposes.
- 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.
