Promethium
Symbol: Pm
Atomic Number: 61
Light Rare Earth Metal
Pm
Overview
Promethium is unique among rare earth elements as it has no stable isotopes and is extremely rare in nature. It's primarily produced artificially in nuclear reactors. Due to its radioactivity and scarcity, practical applications are limited, though it has been used in specialized atomic batteries for spacecraft and in luminous paint for watches and instruments.

Investing in Promethium
- Promethium is not commercially traded due to its radioactive nature and artificial production.
- Laboratory-produced quantities cost tens of thousands of dollars per gram.
- No established market pricing exists due to extremely limited production and specialized uses.
- Only available through specialized nuclear facilities and research institutions.
- Investment exposure is effectively impossible for retail investors.
