WebJan 15, 2024 · The Aufbau principle states that electrons must fill lowest energy shells first. Following the model, electrons fill the 1s orbital with two electrons, then the 2s with two electrons, then the 2p with six electrons, then the 3s with two electrons, etc. There are some exceptions to the Aufbau Principle. WebAfter the 4s is full we put the remaining four electrons in the 3d orbital and end with 3d4. Therefore the expected electron configuration for Chromium will be 1s 2 2s 2 2p 6 3s 2 3p 4 4s 2 3d 9. Note that when writing the electron configuration for an atom like Cr, the 3d is usually written before the 4s.
