Interesting Facts
- Neodymium is not found free in nature, hence it is not a native metal.
- Neodymium metal found in minerals like Monazite and Bastnaesite.
- Rubidium metal is 16th most common element found in the earth crust.
- Rubidium metal also found in minerals as well as seawater.

Uses & Benefits
- Neodymium-Iron-boron alloy is used to make permanent magnets.
- It is used in microphones, Mp3 player, loudspeakers, mobile phones, etc.
- Rubidium's main application is in the glass manufacturing.
- Rubidium can very easily get ionized and hence it is used for ion engines, but it is still less efficient than that of Caesium.
