WebJan 30, 2024 · Figure 2: Periodic table of periods 2-4. ... These are the electrons in the highest energy level, and so it is logical that they will be removed first when the scandium forms ions. And that's what happens. The 4s electrons are also clearly the outermost electrons, and so will largely define the radius of the atom. The lower energy 3d orbitals ... Web3d and 4s have nearly the same energy level. The difference between the two varies from element to element. So, if the two levels are close enough on a particular element, one or two electrons can get bumped up to 4s due to electron-electron repulsion being greater than the difference between the two energy levels. jaxon industries columbia city
