Electronic formulas of atoms of chemical elements
(the layers are arranged in order of filling the sublevels)

To characterize the state of an electron, quantum numbers are used that determine the electron states and the types of atomic orbitals on which they are located. These quantum numbers are the main (n), orbital (l), magnetic (ml), and spin (ms). When composing an electronic formula, the most important are the principal and orbital quantum numbers. The main quantum number determines the energy level of the electron. It corresponds to the period number in the periodic system of DI. Mendeleev and takes integral values: 1,2,3 .... The orbital quantum number determines the shape of the orbitals. It can take integer values: 0,1,2 ... (n-1), which corresponds to the sublevels: s-, p-, d-, f ... The filling sequence of the electron orbitals is determined by the Klechkovsky rule "Electron Filling of Orbitals in an Atom occurs in the order of increasing sum of the principal and orbital quantum numbers n + 1. For the same sum, an orbital with a smaller value of n "is filled earlier. On the basis of this rule, electronic formulas of all chemical elements of the periodic system are compiled. The order of filling the orbitals is as follows
