Richard Wilson relates how the rare, highly radioactive, highly toxic element protactinium puzzled chemists for a long time, and was discovered and named twice from two different isotopes before ...
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. Following this, two groups ...
Atomic Number: 91 Atomic Symbol: Pa Atomic Weight: 231.03588 Melting Point: 2,862 F (1,572 C) Boiling Point: 7,232 F (4,000 C) Word Origin: The word protactinium comes from the Greek protos, meaning ...
Chemists have recently explored protactinium's multiple resemblances to more completely understand the relationship between the transition metals and the complex chemistry of the early actinide ...
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 most ...
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. Found naturally only in ...
When it comes to the elements, humans are pretty good at ensuring that nothing goes to waste. We’ve put nearly every element on the periodic table to work, whether it’s fueling chemical reactions ...
