WebMay 7, 2024 · Exceptions In several cases, the ground state electron configurations are different from those predicted using th periodic table and the Aufbau Principle. Some of these anomalies occur as the 3 d orbitals are filled. For example, the observed ground state electron configuration of chromium is [Ar]4 s1 3 d5 rather than the predicted [Ar]4 s2 3 d4. greek restaurants south bank brisbane
