Protactinium exists in two major oxidation states: +4 and +5, both in solids and solutions; and the +3 and +2 states, which have been observed in some solids. As the electron configuration of the neutral atom is [Rn]5f 2 6d 1 7s 2, the +5 oxidation state corresponds to the low-energy (and thus favored) 5f 0 configuration.
In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule ... Protactinium: 91 7s 2 5f 2 6d 1 ...

As an approximate rule, electron configurations are given by the Aufbau principle and the Madelung rule. However there are numerous exceptions; for example the lightest exception is chromium, which would be predicted to have the configuration 1s 2 2s 2 2p 6 3s 2 3p 6 3d 4 4s 2 , written as [Ar] 3d 4 4s 2 , but whose actual configuration given ...
The ground-state electron configurations of thorium ions are as follows: Th +, [Rn]6d 2 7s 1; Th 2+, ... Like its protactinium(IV) and uranium(IV) analogues, it is a ...
The collapse of the 5g orbital itself is delayed until around element 125 (unbipentium or eka-neptunium); the electron configurations of the 119-electron isoelectronic series are expected to be [Og]8s 1 for elements 119 through 122, [Og]6f 1 for elements 123 and 124, and [Og]5g 1 for element 125 onwards.

Configurations of elements 109 and above are not available. Predictions from reliable sources have been used for these elements. Grayed out electron numbers indicate subshells filled to their maximum. Bracketed noble gas symbols on the left represent inner configurations that are the same in each period. Written out, these are: He, 2, helium : 1s 2
