Answers to Questions
How to encrypt using atomic numbers cipher?
Encryption 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.
Classification was changed in 2016 and the page reflects these updates.
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.
What is the periodic table of elements?
It is a table that arranges the elements in a logical way:
