Cobalt ground state electronic configuration

Practice Exercise Write the ground-state electron configurations for (a) phosphorus and (b) cobalt. 

The ground-state electronic configuration of iron in the solid-state metal lattice is [Ar] 4s 3d . The magnetic moment per iron atom in a cm solid is 2.2 X 10 emu, or approximately 2 Bohr magnetons = 1 x 10 emu). Therefore, there are two unpaired electrons in each iron atom throughout the lattice. By comparison, the fx-B values for cobalt ([Ar] 4s 3d ) and nickel ([Ar] 4s 3d ) arc 1.72 and 0.61, respectively. Since there are five d orbitals and six d-electrons for iron, two separate... 

Octahedral Vanadium(III). It has been pointed out by Jorgensen (19) that the vanadium(III) ion may not be the most suitable example on which to study the reduction of interelectronic repulsion parameters. In principle, both the vanadium(III) and the cobalt(II) ions to be discussed below are configurationally instable owing to the influence of the Jahn-Teller effect (76) on the orbitally d enerate ground states Ti, and respectively. However, in contrast to Ej states, it may be expected that the distortion should be relatively small in electronic Ti, and T g states. Since any indication of a dissymmetry is lacking in the electronic spectra studied here, the influence of the Jahn-Teller effect will not be considered farther.

Write the orbital diagram for the ground state of cobalt. The electron configuration is [Ar]3d 4s. ... 

To do this, we spin-pair the unpaired electron of O2 with one of the two unpaired electrons of the Co(III) configuration of stracture (46). Because structure (47) retains an unpaired electron on the cobalt, it cannot represent the ground-state for any of the adducts which have so far been studied. However, it must...
