The crystal structures that it does exist in also exert forces on promethium’s chemical bonds, obscuring its fundamental ...

Although the Periodic Table of Elements is an impressive achievement of human understanding ... an isotope of Promethium. Once this sample was combined with a ligand to form a stable complex ...

In this research, scientists created a pure sample of the isotope promethium-147. They bonded it with a molecule to form a stable complex in water. Next, they used X-ray absorption spectroscopy to ...
