For a while, I have researched after particles just to get a clear sturcture of them - for the known ones (protons, electrons, neutrons and photons) at least.
As protons, neutrons and electrons are particles of materials, they are called fermions in general. The electrons have a light mass, they are counted to leptons. Neutrons and protons instead have a heavy mass, that is why they are baryons. Moreover, the nucleus of an atom consists of these particles, that is why they are called nucleons too. Protons and Neutrons are consists of quarks, mainly the up and down ones. These quarks in combination with (a protons for instance consists of two up quarks and one down quark) determine the property of a particle. So, is that right when the compound of these quarks in the inner of a particle (neutrons or protons) is changed, the property of these particles are changed too? so a proton can be turned into a neutron and vice versa, the charge included?! the subatomic particles which conncet the protons and neutrons to a nucleus are gluons. As photons are force carrier particles (because of quantised light energy) which are emitted to be accepted by another ones, namely electrons, they are guage bosons.
Of course the order of particle groups would be endless, if another particles (neutrinos, positrons and muons to name but a few), and another factors (spins and interactions) are considered. But in a raw explained way, are my thoughts right?
