Physics asks one of the most profound questions: “What is everything made of?” This article provides a complete explanation and enumeration of all elementary particles within the Standard Model, including every quark, lepton, boson, color state, and antiparticle.
Introduction
The Standard Model of particle physics is our best framework for understanding the fundamental constituents of the universe. It describes elementary particles—the building blocks of matter and the carriers of all known forces (except gravity).
However, when people ask, “How many elementary particles are there?” the answer depends on how we count:
Do we count antiparticles separately?
Do we include the three color states of quarks?
Do we count only distinct types or every physical state?
This article carefully explains both conventions, then lists all 61 distinct Standard Model particle states in one LaTeX-formatted table.
The Core Idea
At the simplest level, the Standard Model contains:
That is the canonical count you’ll see in resources from CERN and the Particle Data Group.
However, when we include:
the three color charges of quarks,
each particle’s corresponding antiparticle, and
the eight color combinations of gluons,
we obtain a more complete total:
Fermions: The Building Blocks of Matter
Fermions are the particles that make up matter. They obey the Pauli exclusion principle, meaning that no two identical fermions can occupy the same quantum state.
They fall into two categories:
Quarks — which feel the strong nuclear force and come in three colors: red, green, and blue.
Leptons — which do not feel the strong force and have no color charge.
Quarks
There are six quark flavors: Each comes in 3 colors () and each has an antiparticle with 3 anticolors ():
Leptons
There are also six lepton flavors: Each has a particle and antiparticle:
Thus, the total fermionic count is:
Bosons: The Carriers of Force
Bosons mediate the fundamental forces of nature. Unlike fermions, any number of identical bosons can occupy the same quantum state.
The bosons of the Standard Model are:
Photon () — 1, self-antiparticle
Gluons () — 8 color charge states
bosons — 2 distinct charged particles
boson — 1, self-antiparticle
Higgs boson () — 1, scalar field particle
Thus:
The Grand Total
Combining fermions and bosons, we have:
This number represents the most complete count of Standard Model states, including colors and antiparticles.

Conclusion
In summary:
Every atom, star, and galaxy arises from these few particles and their interactions. In the grand symphony of the cosmos, just 61 notes compose all that exists.
