I suppose that hadrons are the heaviest.
In the atom this particle is the electron. Generally in the particle physics: photons, gluons, neutrinos.
This particle is the neutron.
A neutron.
For example protons and neutrons are formed from quarks and gluons.
Protons and neutrons are roughly 1800 times heavier then electrons.
Protons and neutrons contain different types of quarks and gluons.
I suppose that gluons are smaller because these particles are massless.
The heaviest subatomic particle is the neutron: 1.00866491600(43) amu.
An atom contain protons, neutrons and electrons; protons and neutrons contain quarks and gluons.
Proton is an elementary particle containing quarks and gluons. Proton is not a radical.
An atom contain protons, neutrons and electrons; protons and neutrons contain quarks and gluons.
The atomic nucleus contain protons and neutrons; protons and neutrons are formed from quarks and gluons.
