Unlocking the Mystery of Promethium: The Rare Earth Element Without Stable Isotopes

For the first time, scientists have characterized a promethium coordination complex, advancing the understanding of challenging lanthanide elements. Promethium, a rare earth element, is unique in that it lacks stable isotopes. As a result, it constantly decays, making it challenging to study. In this research, scientists successfully isolated a pure sample of the isotope promethium-147 […] Read More
