Pm is indeed a 4f4. Neodymium Electronic configuration. Electron Configuration: 1s 2 2s 2 p 6 3s 2 p 6 d 10 4s 2 p 6 d 10 f 4 5s 2 p 6 6s 2; Electrons per Energy Level: 2,8,18,22,8,2 Shell Model ; Ionic Radius: 0.995Å; Filling Orbital: 4f 4; Number of Electrons (with no charge): 60; Number of Neutrons (most common/stable nuclide): 84; Number of Protons: 60; Oxidation States: 3; Valence Electrons: 4f 4 6s 2 Electron Dot Model. The electron configuration for sulfur is [Ne]3s2.3p4. Neodymium – Electron Configuration and Oxidation States – Nd 2020-02-05 by Nick Connor Neodymium is a chemical element with atomic number 60 which means there are 60 protons and 60 electrons in the atomic structure. The electron configuration for oxygen is [He]2s2.2p4. Electronic configuration: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6 4d 10 5s 2 5p 6 4f 4 5d 0 6s 2 >> Back to key information … The tipoff that Ce is incorrect was that Ce is in the first column of the 4f electrons so its ground state configuration should end with 4f1.

The number of electrons is 61 which belongs to promethium, Pm. The electron configuration for oxygen is [He]2s2.2p4. The electron configuration for sulfur is [Ne]3s2.3p4. PLEASE NOTE: The electron configuration has "2p3" and should be "2p6." This list of electron configurations of elements contains all the elements in increasing …
