2 Facts

2.1 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).

Aluminum’s abundance percentage is more as it is found in more than 260 minerals.

Pure Aluminum always reacts with oxygen rapidly.

It is a good conductor of heat and electricity and used in transmission lines.
