How many electrons does scandium have
WebNov 4, 2024 · You may assume that the valences of the elements—the number of electrons with which an atom will bond or form—are those that can be derived by looking at the groups (columns) of the periodic table. While these are the most common valences, the real behavior of electrons is less simple. Here is a table of element valences. 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.
