WebElaborating on our previous studies, we anticipated that replacing two pyridines of a pentanitrogen ligand by two quinolines would enhance the electron affinity of the … WebIron has the lowest electron affinity because it already has a half-filled d-orbital in its outermost shell, which makes it relatively stable. Adding an electron to this already stable configuration would require a significant amount of energy, which is why iron has a low electron affinity. Additionally, the smaller size of the iron atom makes ...
