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. WebApr 5, 2024 · Scandium is one of the chemical elements, also a rare metal found on the earth. In 1871, Dmitry Ivanovich Mendeleyev, a Russian chemist, predicted the existence of this element. ... It is represented by the symbol “Sc”. In the periodic table, the atomic number of scandium is 21.
