How do we know this is true? How do we know that the 4s orbital is actually higher energy Unfortunately there is noД®asy explanation for this but this is the observedД®lectron configuration for scandium. Proton compared to calcium and then there are onceДЄgain many more factors and far too much to There are many other factors to consider so things like increasing nuclear charge. It might be higher in energy for those two electrons, it must not be higher energy overall for the entire scandium atom. Why did those electrons, why did those twoД®lectrons go to an orbital of higher energy? There's no simple explanation for this. It's actually 4s 2, 3d 1 or if you prefer 3d 1, 4s 2 once again with argon in front of it. The electron configuration turns out to be 4s 2, 3d 1. Higher energy orbital so two of those electrons move up to the 4s orbital here like that. Actually two of these electrons actually move up to the You might think it would be argon 3d 3 but that's not what we observed for the electronД¬onfiguration for scandium. My electron configuration like that for scandium. I'm gonna put thoseД®lectrons in the lowest energy level possible here and I'm going to not pair my spins and so I'm going to write All right, so if you thinkДЄbout these three electrons, where are we gonna put them? Well your first guess, if you understand these energy differences might be, okay, well I'm We're talking about onceДЄgain increasing energy and so that's pretty weird. Small energy differences, now the energy of the 4s orbital is actually higher than theД®nergy of the 3d orbitals. When you hit scandium even though these are very Now we have to think about the d orbitals and once again things are very complicated once you hit scandiumД«ecause the energies change. We have three electrons to worry about once we put argon in here like that. For calcium, once we counted for argon we had two electrons to think about. All right, so for potassium, once we accounted for argon, we had one electron to think about.

The electron configurationДЇor calcium two plus would be the same as theД®lectron configuration for the noble gas argon here. The two electrons that we would lose to form the calcium If we lose two electrons, we have a net deposited two charge. With the atomic number of 20, 20 protons and 20 electrons. For the calcium two plus ion, so if you're thinkingДЄbout forming an ion here, we're talking about theД®lectron configurations for a neutral atom meaning equal numbers of To go into the 4s orbital as well and so we pair our spins and we write the electron configuration for calcium as argon in brackets 4s 2. All right, we have one moreД®lectron then potassium and so that electron's going We have increasing energy and that electron goes into a 4s orbital so the complete electron configuration using noble gas notation for potassium is argon in brackets 4s 1. Potassium has one more electron than argon and so we put that extraД®lectron into a 4s orbital because for potassium the 4s orbital is lower energy than the 3d orbitals here. We know argon has 18 electrons and potassium has 19 electrons. Notation to save some time, we work backwards and theДЇirst noble gas we hit is argon, so we write argon in brackets. Potassium and for calcium but let's do it again really quickly because it's going toДЄffect how we think about the d orbitals and so we find potassium which is in the fourth
