Interesting Facts
- Strontium element is softer than Calcium.
- Silvery Strontium turns yellow, if exposed to air.
- Plutonium metal if obtain from ores of uranium metal.
- Plutonium metal is very sensitive to the change in atmospheric conditions like temperature and pressure.

Uses & Benefits
- Strontium metal is used to producing ferrite magnets as well as refining zinc.
-
By-product of nuclear reactors called Strontium-90 is a radioactive isotope; it is absorbed by tissues and destroys bone marrow and cancer growth.
- Plutonium was used in atomic bombs and still it is being used in various weapons and Ammunition industry.
-
It is also used in nuclear power plant as source of energy for space missions.
