What is the configuration of Cobalt’s electronic orbitals?

Receipt

The heating of a mixture of cobalt (II) oxide and aluminum oxide at a temperature of 1200 to 1300 ° C:

CoO + Al2O3 = Co[Al2O4]

It is prepared by heating alumina (Aluminum oxide) or sodium aluminate with halide salts of cobalt.

2AI2(SO4)3 + 2Co(NO3)2 → 2Co(AlO2)2 + 6SO3 + 4NO2↑ + O2
