WebApr 11, 2024 · Promethium $\text { (Pm) }$ is the only lanthanide that exhibits radioactivity. It is one of the two elements among the first 83 elements. It does not have a stable or long-lived isotope. The promethium isotope (promethium-146) is unstable. The primary decay product of promethium is neodymium $\text { (Nd) }$ and samarium$\text { (Sm) }$.
