Recently, I was going through the magical materials that existed in one of my fantasy settings. It was all going swimmingly, when a thought occurred to me: "You know, I should figure out how chemistry works with these things". I have been tortured and racked ever since trying to get something respectable to work, but I think I have the start of a solution:
I should invent an additional periodic table.
Even leaving aside the patachemistry, I know it's a laughable amount of work. But that leads us to my question:
What principles should I keep in mind during my project?
I'm not trying to invent new materials that could actually exist on the real periodic table; I know that trying to squeeze more elements onto it is impossible, so I've handwaved it and said "magic can be used to ascend ordinary elements onto this new table". The new elements don't use the same protons or neutrons as the originals, so I think that covers their "being able to exist". The problem comes from wanting to be unique. I do not want to have a one-to-one correspondence between the actual periodic table and my creation. That means that not only are there real elements that can't be ascended, there are ascended elements that can't be created (ignoring for now how they come into being). I could even change the shape of the table as I see fit.
I don't have too many pata-elements invented yet, and I would like to know how to stitch my new periodic table together so that it looks authentic. I want to know what I should keep in mind with periods and columns, for example, or where I could place liquids. How do I decide what everything should weigh, where should the gases go, things like that.
In short, what principles should I keep in mind while designing a pataphysical periodic table?
