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

Chemistry is the science of elements and how they form bonds to each other using the electromagnetic force through electrons–the nucleus while important in electron configuration and mass is really of only indirect importance. It is also the study of the properties of the elements and their compounds (molecules).

There is “nuclear chemistry” which is commonly considered a sub-field of chemistry. It deal mainly in nuclear reactions–primarily radioactive decay. This isn’t really chemistry, although some chemical processes may be used. I think it is more physics, although some may prefer to look at it as a physics/chemistry hybrid.
