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).
- Neodymium is not found free in nature, hence it is not a native metal.
- Neodymium metal found in minerals like Monazite and Bastnaesite.
