Standard model

12 Fermions, 6 leptons and 6 quarks, make up matter. Fermions have half-integer spins. Every Fermion has an antimatter (anti-fermion) counterpart.

Bosons have integer spin. 4 Gauge bosons create forces. Higgs boson gives particles mass.

Chemistry uses electrons and photons (electromagnetic force). Nucleus is up/down quarks and gluon.

In diagram below the particles of the standard model are shown with masses (in MeV) in the upper right. The Fermions make up the left three columns (three generations); the bosons populate the right two columns.

Only first generation Fermions are stable.

PS. This was weirdly hard for me to assemble. Image is from fermilab I think.
