explain the stability of d3 and d4 orbitals of chromium by using exchange energy

Answer 1

this can be directly appreciate by considering the simplest case of two hydrogen atoms first had at large distance and then Road closer together for the electronic wavefunctions centred on the two atoms to overlap. the consequent splitting of the energies of the two particle singlet and triplet States is you to exchange. through this the singlet state established as the revenant details you may consult for instance the book solid state.
