Fermions are any particles which aren't bosons, and are themselves split into 2 groups,
Leptons and Quarks.

Quarks
Quarks, are the particles which form the protons and neutrons as well as many other, but
much rarer particles. There are 6 flavours of quark, 3 positively chared. The Up, Charm…

Quark Confinement
In theory if you provide enough energy to a Baryon, you could separate it to get an
individual quark. The problem with this is though that because quarks are held together by
the nuclear strong force, a very large amount of energy is required for this, and before…
