Promethium
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.
