![]() These anomalies generally involve the promotion of an s electron to the next d shell in order to achieve a full or half-full d shell. If we can half fill 3d, it will fill BEFORE 4s. Lanthanum is outside this generalization, but is included in the table for its. Remember, even though in the filling order we put d electrons after p, a 3d electron is still in the same shell as 3p, and 4s is further away. The ground state electron configuration of the lanthanide elements are generally of the type (Xe)4f n 6s 2. Electrons are “lazy” and will do whatever places them in the lowest energy state = which is the most stable state A sublevel which is exactly half filled is more stable than a partially filled sublevel which is not half full.ģ. Completely filled sublevels ( like the d sublevel) are more stable than partially filled sublevels.Ģ. Why? It’s a little complicated, but the following may help make logic of these anomalies:ġ. When a transition metal loses electrons to form a cation, the first two electrons to be removed are the s ones, then the d. Some elements, however, do not follow this filling order exactly. For example, the valence electron for Calcium which has 20 electrons is 4s2, but Scandium which has one more electron has a valence electron of 3d1. This is exactly how the periodic table is arranged, because the valence electrons go up the same way on the periodic table. In class, you learned that the energy levels of electron configuration fill up according to their filling order which can be determined by the diagonal rule. Monir This may be you: Ahhhhh!!!!! I feel like I just figured out how electron configuration works, and now you tell me things like Fe3+ doesn’t follow the same rules?! What do you mean when you say this is the electron configuration?! That’s not Aufbau! Somebody help me!
