Aufbau Principle Exceptions Like most rules, there are exceptions. Half-filled and completely filled d and f subshells add stability to atoms, so the d and f block elements don't always follow the principle. For example, the predicted Aufbau configuration for Cr is 4s 2 3d 4, but the observed configuration is actually 4s 1 3d 5.
What is the basis for exceptions to the Aufbau diagram? Exceptions to the Aufbau principle are based on the fact that a few atoms are more stable when their electrons fill or half-fill an electron shell or subshell. According to the Aufbau principle, these electrons should always fill shells and subshells according to increasing energy levels.

The aufbau principle, from the German Aufbauprinzip (building-up principle), also called the aufbau rule, states that in the ground state of an atom or ion, electrons fill subshells of the lowest available energy, then they fill subshells of higher energy. For example, the 1s subshell is filled before the 2s subshell is occupied. In this way, the electrons of an atom or ion form the most ...
