ELI5: Why can’t we just continue to make new elements? Why can’t we just keep adding atoms and electrons?

Well to make new elements, you don’t add atoms or electrons. You add protons to the atom, each new proton is a new element.

And the reason is because as the elements get larger and larger, the nucleus becomes more and more unstable as all the positively charged protons are trying to repel away from each other, and when there’s a lot of them they’re able to overcome the strong nuclear force holding them together.
