WebbIn scandium and the other d block members of period 4, the 3d is lower in energy than the 4s. However, because the 3d orbitals are smaller and more closely packed than the 4s, the electron-electron repulsion that occurs in the 3d subshell is enough to make it possible for 1 or 2 electrons to have a lower energy by occupying the 4s.
