This ground-state electronic … WebJan 31, 2024 · The reason we see these Aufbau's principle exceptions in transition metals is because the 4 s and 3 d orbitals are very similar in energy. In chromium, having a 4 s 2 3 d 4 configuration results in electron-electron repulsion due to the two electrons in the 4 s orbital. For this reason, chromium adopts a 4 s 1 3 d 5 configuration, in which each ... bautista lawyer
