The Radiochemistry of
Protactinium
Sodium hydroxide precipitates protactinium from a citrate, but not from a tartrate
solution. With H2O2 in large excess, protactinium(V) forms a precipitate which is
insoluble in NH^OH and NaOH. The precipitate is soluble in dilute H,,SO^ only ...

Standard Potentials in Aqueous Solution
protactinium is rapidly oxidized by air. In very acidic media ([H+] > 2 M) the
predominant tetravalent species is the ion Pa**"I", which appears to be less
easily hydrolyzable than pentavalent protactinium. In the +5 oxidation state the
protactinium ...

5.3 Protactinium K. Fajans and O.H. Gohring describe the discovery of
protactinium (Pa-234) in 1913. They gave the new element the name brevium. In
1918, O. Hahn and L. Meitner have isolated the longer living isotope Pa-231. Pa-
231 has ...

Protactinium is the third actinide and the first in the group to have electrons in the
5f shell. The electron configuration of its ground state 2 1 2 is [Rn]5f 6d 7s , and
its major oxidation state is +V. Although the oxidation state +IV is also possible, ...
