![]() We're talking about onceĪgain increasing energy and so that's pretty weird. Small energy differences, now the energy of the 4s orbital is actually higher than theĮnergy 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 scandiumīecause 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. #Antimony orbital diagram plus#The electron configurationįor calcium two plus would be the same as theĮlectron 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 thinkingĪbout forming an ion here, we're talking about theĮlectron 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 moreĮlectron 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 extraĮlectron 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 theįirst 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 toĪffect how we think about the d orbitals and so we find potassium which is in the fourth We've already looked at the electron configurations for ![]()
