WebJul 19, 2009 · The valence of scandium is 3 (some exceptions possible). How many electrons are in the scandium valence shell? The element scandium has 21 electrons. WebIn 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.
