To expand on this, there aren’t any gaps left so the only new ones will be increasingly heavyweight and have vanishingly short half-lives, which means that they are increasingly difficult to synthesize and detect. In theory there is an island of stability once we can synthesize sufficiently heavy elements, but it seems pretty far off.
The last new element (afaik) was like… 2016? So depends on what counts as new I suppose :3
