What is the periodic table of elements? (Definition)
The periodic table of the elements is a table from Dmitri Mendeleïev that arranges the elements in a logical way using their properties and number of protons:

What is the atomic number in the periodic table?
The atomic number in the periodic table represents the number of protons present in the nucleus of an atom. It is also the number of electrons present in the neutral atom.
How to encrypt using atomic numbers cipher?
Encryption using atomic codes consists in substituting letters (or group of letters) representing a chemical symbol by its corresponding atomic number. (Hydrogen H = 1, Helium He = 2, etc.)
Example: FUSION can be decomposed in F 9 (Fluor), U 92 (Uranium), Si 14 (Silicium), O 8 (Oxygen), N 7 Nitrogen, so 9,92,14,8,7.
All words cannot be crypted as the classification does not contain all alphabet letters. In order to increase the possibilities, it is possible to use the inverse symbols: 'He = 2' and eH = 2' (with an apostrophe) (thank you Arash / @arashimidos)
How to decrypt atomic numbers cipher?
Decryption requires to know the periodic table of elements (1 = H, 2 = He, etc.)
Example: 20,37,8,7 for Calcium CA, Rubidium RB, Oxygen O, Nitrogen N gives CARBON
How to recognize an atomic number substituted text?
The message is made up of numbers between 1 and 118.
The painting is associated with its author: Dmitry Ivanovich Mendeleev (sometimes written Dimitri) a Russian chemist.
The concepts of nucleus (nuclear), atomic bomb, elementary particles (proton, electrons, neutrons), chemistry, molecules, etc. are clues.
