Nobelium is a member of the actinide series of elements. The ground state electron configuration is assumed to be (Rn)5fl47s2, by analogy with the equivalent lanthanide element ytterbium ([Kr]4fl46s2) there has never been enough nobelium made to experimentally verify the electronic configuration. Unlike the other actinide elements and the lanthanide elements, nobelium is most stable in solution as the dipositive cation No ". Consequently its chemistry resembles that of the much less chemically stable dipositive lanthanide cations or the common chemistry of the alkaline earth elements. When oxidized to No, nobelium follows the well-estabhshed chemistry of the stable, tripositive rare earth elements and of the other tripositive actinide elements (e.g., americium and curium), see also Actinium Berkelium Einsteinium Fermium Lawrencium Mendele-vium Neptunium Plutonium Protactinium Ruthereordium Thorium Uranium. 

The following elements also have the same electronic configuration as actinium (i.e. 5s 5pl) in their outer-most electronic orbitals, while the inner 4d orbitals are being filled, on going from element to element. Neptunium, Plutonium, Americium, Curium, Berkelium... 

The similarities and differences between the electronic configurations for the lanthanides and actinides (see tables 1 and 23) do provide some insights into the physics and chemistry of these two f series of elements. Beyond plutonium the actinides tend to be more lanthanide-like in behavior, although there are still notable differences between the two series of elements. For the actinide oxides whose solid-state properties have been studied (e.g., through ES2O3), one of the major differences is the greater ease... 

In the lighter aetinides, uranium, neptunium and plutonium compounds are more thoroughly investigated. Tetravalent Pa eompoimds, probably in the form of Pa02, could become intermediate valent the electronic configuration would then be the same as in Pr02, with one or a fraction of one f electron.
