Full electron configuration of cobalt11/23/2023 ![]() Usually, it is expected that electrons will be removed from the same subshell but in the case of Co 3+ 1 electrons are removed from 4s and 2 electrons are removed from the 3d orbital. The electron configuration of the Co 3+ ion is: Cobalt orbital diagram Cobalt 3+ electron configuration The ground state Co orbital diagram is 2, 8, 15, 2 which is a broader representation of the electron configuration involving only energy levels following the octet rule or K, L, M, N rule. In the case of Co 1+ ion coordinated to ligands with possible octahedral symmetry, there will be a splitting of ground state energy levels into e g and t 2g set. The excited state electron configuration of Co depends upon the type of complexation it is undergoing with ligands, hybridization, and symmetry. The ground state electronic configuration of Co is:ģd 74s 2 Ground state electronic configuration of cobalt The excited state of cobalt electron configuration Ground state cobalt electron configuration The unabbreviated electron configuration of Co is:ġs 22s 22p 63s 23p 64s 23d 7. Cobalt unabbreviated electron configuration The rest of the configuration is written afterward following Aufbau’s n+l rule. Here Ar is designated as a noble gas argon configuration which is up to 18 electrons. The electron configuration notation of Co is: Cobalt electron configuration according to Aufbau principle Cobalt electron configuration notation Completing the electron count and fulfilling the energy considerations now there will be filling of 3d orbital (3d 7).Following the n+l rule now there will be a filling of 4s first due to low energy (4s 2).After 3s 2 there is a new orbital that can hold 6 electrons (3p 6).Next, there will be a new energy shell that has a maximum capacity of 2 electrons (3s 2).The third orbital has the same energy shell and can withhold 6 electrons (2p 6).The second orbital is 2s which again has 2 electrons (2s 2).The first orbital is 1s which can hold 2 electrons (1s 2).The electronic configuration of Co diagrammatically is: The atomic number of cobalt is 27 which implies it has 27 electrons. Keeping in mind the quantum numbers the electron configuration of cobalt is 1s 22s 22p 63s 23p 64s 23d 7.The convention of writing electron configuration is followed that is writing of energy shell first followed by the orbital and then electron in superscript.The electron configuration is written by following Aufbau principle and considering the n+l rule for energy.This is significant to write electron configuration. The atomic number of Co is 27 which implies that there are 27 electrons in cobalt.The electron configuration of Co can be written in certain steps. How to write cobalt electron configuration? Let us throw light on its electronic factors like configuration, orbital diagrams, etc. Various oxides, halides, coordination complexes, and organometallic complexes of cobalt are discovered and used. It is a hexagonal closed pack (hcp) crystal structure that is solid in normal conditions and is isolated by the process of smelting.Ĭobalt is a versatile and ubiquitous metal because of its varied application. Cobalt is a very hard, lustrous bluish grey metal that belongs to d-block and is under the category of transition metals. The electron configuration of cobalt is 1s 22s 22p 63s 23p 64s 23d 7. Let us discuss the electronic configuration of Cobalt. Phenom., 1980, 21, 275.Cobalt is a chemical element with the symbol Co which is found in the earth’s crust in combined form.

The binding energies are quoted relative to the vacuum level for rare gases and H 2, N 2, O 2, F 2, and Cl 2 molecules relative to the Fermi level for metals and relative to the top of the valence band for semiconductors. All values of electron binding energies are given in eV. 1967, 47, 1300.Įlectron binding energies Electron binding energies for cobalt.
