What are some fun facts about protactinium?
Other Interesting Protactinium Facts Protactinium has no stable isotopes. Handling of protactinium is similar to that of plutonium, due to its potent radioactivity. Even if it was not radioactive, protactinium would present a health risk because the element is also a toxic metal.
Why is protactinium important?
A silvery, radioactive metal. Protactinium is little used outside of research. Protactinium has no known biological role. It is toxic due to its radioactivity….

What are the characteristics of the element protactinium?
Characteristics: Protactinium is a very rare shiny, silvery, highly radioactive metal that tarnishes slowly in air to the oxide. Almost all naturally occurring protactinium is the 231 isotope. It emits alpha radiation and is produced through the decay of uranium-235.
Is protactinium toxic?
Protactinium is one of the rarest and most expensive naturally occurring elements. The element is an α-emitter and is a radiological hazard similar to polonium. Protactinium is a highly toxic and radioactive rare earth metal that requires special handling.
What is protactinium made from?
Nearly all natural protactinium is protactinium-231. It is an alpha emitter and is formed by the decay of uranium-235, whereas the beta radiating protactinium-234 is produced as a result of uranium-238 decay.
Does protactinium have any uses?
Currently, protactinium is usually extracted from used nuclear fuel. Due to its scarcity, high toxicity, and high radioactivity, protactinium has no current practical uses other than basic scientific research.
What is protactinium natural state?
Cite. Protactinium is a chemical element with symbol Pa and atomic number 91. Classified as an actinide, Protactinium is a solid at room temperature.
Who created protactinium?
Protactinium metal was first prepared (1934) by American chemist Aristid V. Grosse. The first isotope, protactinium-234, was discovered (1913) by American chemists Kasimir Fajans and O.H. Göhring.
Which is the most useless element?
Protactinium (formerly protoactinium) is a chemical element with the symbol Pa and atomic number 91.
What element has no uses?
Nobelium
Nobelium has no uses outside research. Nobelium has no known biological role. It is toxic due to its radioactivity. Nobelium is made by bombarding curium with carbon in a device called a cyclotron.
What is the half life of protactinium 231 Pa?
Almost all naturally occurring protactinium is 231 Pa. It has a half-life of 32,700 years and is an alpha emitter formed by the decay of 235 U. Other uranium decays produce isotopes of protactinium.
What is Protactinium-234m?
Protactinium-234m is a member of the uranium series with a half-life of 1.17 minutes. It was discovered in 1913 by Kazimierz Fajans and Oswald Helmuth Göhring, who named it brevium for its short half-life.
What are the isotopes of protactinium?
The only naturally occurring isotopes are 231 Pa, which occurs as an intermediate decay product of 235U, 234 Pa and 234m Pa, both of which occur as intermediate decay products of 238U. 231 Pa makes up nearly all natural protactinium. The primary decay mode for isotopes of Pa lighter than (and including)…
What is the history of protactinium?
Facts About Protactinium. Discovery: The existence of protactinium was predicted in 1871 by Dmitri Mendeleev. Discovery of the element is attributed to Otto Hahn and Lise Meitner, who discovered another isotope of protactinium, 231 Pa in 1917. The element wasn’t isolated until 1934, by Aristid von Grosse.
