quark and anti-quark making the composition of protons and neutrons.

matter made up of one type of particle is called ____________ .
We could say what the second smallest piece of matter if we knew what the smallest piece of matter was. Since the smallest pieces of matter known are quarks-down, strange and bottom have the lowest charge -3, they can be regarded as the first, second and third smallest particles.
