Ideas, solely related on the nuclear shell model, fail to give an interpretation of the experimental central role of ₅₄Xe in the asymmetric fission of actinides. The same is true for the β-delayed fission of ¹⁸⁰Tl to ⁸⁰Kr and ¹⁰⁰Ru. The representation of the natural isotopes, in the Z-Neutron Excess plane, suggests the importance of the of the Neutron Excess evolution mode in the fragments of the asymmetric actinide fission and in the fragments of the β-delayed fission of ¹⁸⁰Tl. The evolution mode of the Neutron Excess, hinged at Kr and Xe, is directed by the 50 and 82 neutron magic numbers. The present isotope representation offers a frame for the interpretation of the post fission evaporation of neutrons, higher for the A_L compared to the AH fragments, a tenet in nuclear fission. Further enlightened is the functional meaning of the 50 proton magic number, marking the start of the yield rise of the A_H fragments in actinide fission.
