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).
- Manganese is an essential trace element in all forms of life.
- Manganese metal oxidizes very easily, but it does not fuse that easily.

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.
- This metal is very brittle hence it mostly not used as a pure metal, but its alloys are very useful
- Its alloy Manganese steel is extremely strong and used in railway tracks, safes, prison bars and riffle barrels.
