Why is the Study of Sub-Atomic Particles a field of Physics and not Chemistry?

Question

I see sub-atomic particles is studied as “Particle Physics”

If the study of the properties of elements, compounds, reactions etc are a field of Chemistry then why is the study of sub-atomic particles (quarks, neutrinos, gluons) and their properties mostly done by Physicists (Particle Physics)
?

Answer 1

At the most basic level, chemistry is the study of electron interactions. Neutrons & proton have nothing to do with the actual interactions (the number of protons relates to the number of electrons on the atom in the base state, but that’s it). Once you know how many electrons are in which shells, and the atomic weight, you know everything a chemist needs to know.

There is nothing a chemist needs to know about how protons or neutrons or any other particle are made/interact.
