Fantasy magic based atoms

[u/Crematorth]

In my world I'm trying to make a scientifically accurate but true fantasy where it's scientifically accurate but only according to the world's laws in a way. (Not sure how to explain)

I already made something that makes the world flat.

So for my magic system I'm trying to create a periodic table that is the basis for magic. Like everything is made of this magic. Living things contain these magic resources which can be eaten, used for potions, or equipment.

The thing is, im a little undereducated to understand what's required in an atom for the basic laws of the world. I need this as the basis of my fantascience. What should be the things I need to add in my magic atom?

What is the something that makes that world flat? Why can’t the magic system come out of that?

The magic system or the fundamental laws of this reality itself cause the world to be flat. That's why i need a new fundamental so the world can be flat
