The lowest energy orbitals must be filled first. For example the 1s orbital is filled and then we can fill the 2s orbital and go on to the 2p orbitals. The filling order follows: 1s→2s→2p→3s→3p→4s→3d→4p→5s→4d→5p→6s→4f→5d→6p→7s→5f→6d→7p E...
What is the electron configuration and orbital diagram for a phosphorus atom? What are the four quantum numbers for the last electron added? Solution The atomic number of phosphorus is 15. Thus, a phosphorus atom contains 15 electrons. The order of filling of the energy levels ...

A dashed electron in the \({{{\rm{d}}}_{{{\rm{z}}}^{2}}\) orbital denotes additional electron filling upon Fe intercalation, concomitant with charge transfer to 2H–TaS2. g Qualitative representation of the density of states of Fe-intercalated 2H–TaS2. Full size image A quantitative...
Notice that the carbon atoms in the structural models (the ball-and-stick and space-filling models) of the pentane molecule do not lie in a straight line. Because of the sp3 hybridization, the bond angles in carbon chains are close to 109.5°, giving such chains in an alkane a zigzag ...
We also add the atomic orbitals 1E1a and 2E1a to the valence band (which do not not trivialize the fragile topology) and a A1a orbital to the conduction band. Note that A1a would trivialize the valence band. To construct the non-interacting Hamiltonian H0, we choose all bands to be ...

Potassium's electron sublevels will be: 1s2 2s2 2p6 3s2 3p6 4s1 For some individual atoms with more than 20 electrons the 3d orbitals may fill before the 4s orbitals. Also, there may be other exceptions to this filling order, as discussed in the comments section for iodine. ...
