The first isotope of protactinium (234mPa) was discovered by Kasimir Fajans and Otto Gohring in 1913.
The isotope 231Pa of protactinium was discovered by Austrian/Swedish physicist Lise Meitner and by Otto Hahn, a German physical chemist in 1918 and simultaneously by Frederick Soddy and John Cranston.
Who named it? The International Union of Pure and Applied Chemistry (IUPAC) often discusses the appropriate name for an element.
it was discovered by a couple of scientist on an expedition
it was discovered in 1913
Protactinium have no odor.
Protactinium is a reactive metal; protactinium react with water vapours, acids, oxygen, halogens,etc.
Because protactinium is extremely radoactive.
At room temperature protactinium is a solid metal.
Protactinium has a metallic appearance.
Protactinium was discovered in 1913 by Fajans and Gohring in Karlsruhe, Germany.
Protactinium was discovered in 1913 by Fajans and Gohring in Karlsruhe, Germany.
The chemical symbol for protactinium is Pa because Pr, Po, and Pt were already taken. Protactinium was discovered in 1913. Praseodymium (Pr, discovered in 1885), polonium (Po, discovered in 1898), and platinum (Pt, known at least since the 1500s) were already discovered and named. The symbol Pa uses the first unused letter (a) in protactinium's name.
Crookes observed the first an isotope of protactinium but neglected this.Fajans and Gohring discovered another isotope and confirmed protactinium as new element.
The first isotope of protactinium (234mPa) was discovered by Kasimir Fajans and Otto Gohring in 1913 (Germany). The isotope 231Pa of protactinium was discovered by Austrian/Jewish physicist Lise Meitner and by Otto Hahn, a German physical chemist in 1918 and simultaneously by Frederick Soddy and John Cranston (England). Protactinium exist in extremely low concentrations in uranium ores (approx. 3 mg/kg).
