This version of the periodic table shows periodicity using quantum numbers. Each plate is arranged according to the principal quantum number . Different colors represent different subshells , , , , that is, values of quantum number. Yellow stands for -orbital for alkali metals and alkaline earths; green for -orbitals, that is, the case of nonmetals and semiconductors; pink for -orbitals corresponding to transition metals; and blue for -orbitals in lanthanides and actinides. Moving from top to bottom represents the quantum number and right to left the quantum number .
