Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences and their collaborators have synthesized a new isotope—protactinium-210—for the first time. It is the ...

Scientists demonstrated that a positively charged protactinium dioxide ion may not exist in aqueous solution like other highly charged actinides, such as uranium and plutonium.

Kasimir Fajans and O.H. Göhring first produced protactinium-234 in 1913 while examining the radioactive decay of uranium. They named the element brevium, which means brief.
