# Periodic Table Cipher

Results
Tool to convert atomic numbers into letters. In the periodic classification of elements or Mendeleiev table, chemical elements are ordered by atomic number and associated to a symbol from 1 to 3 letters (and be used in a cipher).
Summary

## Periodic Table Encoder

### 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. 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)

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:
