'WHAT NOT TO SUGGEST
-Elements that follow the rules of chemistry, for example, elements that would ionize, bond, be different pH levels of acids/bases, etc., unless they provide a new innovation that will enable many new, useful creations. We don't need aminoethylpiperazine to react with carminic acid to form tetrachloromethane.
-Elements similar to ones we already have (TNT, for example, would be about the same as rubidium).'
There is also already an elements suggestion thread that you are supposed to post it.

We suggested Radium (Solid and static, produces neutrons from decay. Decays into radon gas) Radon is a gas that slowly gives out Neutrons. I think this would add a kind of new level of radioactivity to TPT.
