Interesting Facts
- Rubidium metal is 16th most common element found in the earth crust.
- Rubidium metal also found in minerals as well as seawater.
- Yttrium Metal is highly toxic.
- Yttrium Metal is highly reactive in nature hence not found free in nature.
Sources

Uses & Benefits
- 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.
- Yttrium metal is used in different alloys, as it increases the strength of aluminum Magnesium alloy. It is used for radar microwave filter.
-
It is also used as a catalyst in ethene polymerisation.
