Both of the configurations have the correct numbers of electrons in each orbital, it is just a matter of how the electronic configuration notation is written ( here is an explanation why ). Electron Configuration and Oxidation States of Iron. of Fe is 26. 19: 83–192. Electron configurations are the summary of where the electrons are around a nucleus. In many cases, multiple configurations are within a small range of energies and the irregularities shown above are quite irrelevant chemically. The electronic configuration for the first 26 electrons, and so therefore iron, is Fe 1s2 2s2 2p6 3s2 3p6 4s2 3d6. The complete shell of element 172 is not easily recognisable because of the p-orbital splitting: the 8p and 9p orbitals are split into more (p1/2, two electrons) and less (p3/2, four electrons) stabilised parts. Here is a summary of the types of orbitals and how many electrons each can contain: So based on what we know about the quantum numbers and using the char… When Fe+ loses one electron = 1s2 2s2 2p6 3s2 3p6 3d6, 4s1. Re: Electron Configuration for Fe 3+ Post by Rachel Wile 2D » Fri Nov 04, 2016 4:17 am You take electrons out of the 4s orbital, before you take them out of the 3d orbital, because it is lower energy to have them in the 3d orbital in comparison to the 4s.
