What is the ground-state electron configuration of chromium (Cr)?. 1s22s22p63s 23p63d104s2
Fe: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 6 4s 2; Fe 3+: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5; The 4s electrons are lost first followed by one of the 3d electrons. This last bit about the formation of the ions is clearly unsatisfactory. We say that the 4s orbitals have a lower energy than the 3d, and so the 4s orbitals are filled first.

The Madelung rule gives the order: 1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p. There are no known elements that, in their ground state, have electrons in a subshell beyond the electronic configuration and the electrons are filled up according to the energy of the levels as: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f.

ex 4s fills before 3d, because 4s has less energy than 3d. It must fill first. Electrons fill the sublevels in energy order 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f 6d 7p. If we add the number of electrons that each sublevel holds it looks like this: 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 6 5s 2 4d 10 5p 6 6s 2 4f 14 5d 10 6p 6 7s 2

Den elektroniska konfigurationen av en atom där alla orbitaler är fyllda kommer att ha följande form: 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 6 5s 2 4d 10 5p 6 6s
Rule 2 - Pauli Exclusion Principle - Only two electrons are permitted per orbital and they must be of opposite spin. If one electron within an orbital possesses a clockwise spin, then the second electron within that orbital will possess a counterclockwise spin.
