A valence electron is an outer shell electron and may participate in the formation of a chemical bond. Nb atom DIRAC presently does not perform an open-shell Hartree–Fock in a strict sense, rather an average-of-configuration calculation, which amounts to the optimization of the average energy of a set of configurations (or determinants) generated from the specification of a given number of open shells and their electron occupations. The electronic configuration of Nb is {eq}Kr4{d^4}5{s^1} {/eq}. A simple transformation of Nb–Co 4 N hierarchical porous nanosheets successfully achieves efficient electrocatalysis for water splitting with a large number of H 2 and O 2 bubbles released from the … transition metal, which is often found in the pyrochlore mineral, Schematic electronic configuration of niobium. Overall, these results show that the Nb-doped WS2 is homogeneous and its electron structure can be modified in a controlled manner by changing the amount of Nb dopant.

Re: Electron Configuration of Nb Post by Patrick Chin 1F » Sat Oct 25, 2014 10:59 pm This is one of the many exceptions on the periodic table, because the energy gap between the 4d and 5s orbitals is small enough for the electron to be pulled from the 5s orbital due to electron repulsion, sort of like Hund's rule except applied across orbitals.
