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

Because it was more important to Physics.

Chemistry can be studied without needing to understand particles. The reactions they study don’t require a knowledge beyond atoms, the same way a chef needs to be able to cook a steak but not understand the reproductive system of a cow

But physicists kept finding things they couldn’t explain, and kept researching. They stumbled upon sub+atomic particles and kept studying them, and their interactions, to see what their existence meant for their theories. Eventually it grew into a field of study in its own right, and stayed with physics.
