If the type of element is directly correlated with its number or protons/neutrons/electrons, why aren't there infinite elements and why is 'discovering' a new one a big deal?

There are not necessarily infinitely many elements that can exist, because eventually there will be a point where the system is so heavy that it won’t be able to sustain bound states if you add anymore nucleons.

Discovering a new one is a big deal because we’ve already discovered all the ones that aren’t extremely difficult to produce.
