Interesting Facts
- Americium metal is produced by bombarding Plutonium with Neutrons.
- Americium metal was discovered as a by-product while testing an atomic bomb (Manhattan Project).
- Dysprosium acts stable in air at room temperature.
- Dysprosium behaves very much like paramagnetic metal.

Uses & Benefits
- Americium metal is used in smoke detection alarms.
-
In the future, this metal has a potential to be used in batteries of spacecrafts.
- Dysprosium metal is highly reactive due to which it pure form is not as usual as its alloy.
-
Thi metals alloy is used in magnate as it is resistance to high temperature.
