An elementary particle is a subatomic particles whose structure is unknown, however, there is string theory; claiming that all matter in the universe and subatomic particles are made out of 11-dimensional strings that vibrate in different portions of energy.
There are six «flavors» of quarks:
There are two down quarks and one up quark in a neutron and two up quarks and one down quarks in a proton.
Leptons are elementary particles (fermions) with spin 1/2 that are not affected by strong nuclear forces. They include electrons, as well as neutrinos, which only interact by gravity.
Bosons include fundamental particles such as photons (which make up Light), W and Z bosons, and the Higgs Boson, which is responsible for mass.
