I recently asked this about why we call things "isotopes" and "elements" (atoms) instead of just having it be a bunch of particles bundled together in different numbers.
This makes me wonder about the definition of Chemical, which Wikipedia has sort of a circular definition. A chemical cannot be broken into elements (atoms) unless breaking chemical bonds (basically the definition)....
So atoms have protons and neutrons (and electrons) that are bound by "atomic bonds". I'm not sure that's correct. So strong force holds a single together. But not sure what holds protons together, maybe that's the weak force. Then "chemical bonds" are between electrons between atoms. My question is, why not just get rid of the distinction of calling things "protons vs. atoms vs. chemicals", and just say there are "particles" which bundle together. They bundle into group 1 (atoms), and group 1's bundle into group 2's (chemicals), but really it's all just particles that are all interacting.
So this makes me wonder, what exactly a chemical is. It is a stable particle system essentially, where atoms combine into larger chunks.
