WebDec 20, 2015 · So the Madelung rule was devised to try to rationalize the concept (quantum numbers) to the observations (the experimental data). This means that the Madelung Rule can, and does, have its own exceptions, like copper. If we went by the Aufbau principle, copper ought to have an electron configuration like this: 1s 2 2s 2 2p 6 3s 2 3p 63d104s1 .

WebWith Hund's rule [ 10, 11, 12] and Pauli’s exclusion principle [ 13], the Madelung-Klechkowski rule is one of the basic tools for predicting the filling of atomic orbitals. The theoretical justification of this rule [ 14] is more … WebFeb 13, 2024 · The reason for such exceptions is the electrons in an atom want to reach the lowest energy level by minimizing the repulsion. One of the solutions to this problem is the Madelung rule, named after Erwin Madelung. It is not a universal rule but very helpful. The rule states the lower the value of n + l, the lower its energy.
