Express Your Message as Atomic Weights

The Element Cipher transforms your words into strings of element names and then converts those to numbers that are based on the atomic weights for those elements. It’s a fun little chemistry-themed encoder. Type a phrase and watch it translate into a sequence of elemental values that hides your message in plain sight. Decode it back and your text reappears from the atomic haze!
