a family of subatomic particles

Fermions are a family of subatomic particles that include electrons, protons and neutrons, but they also appear in nature in many lesser known forms such as the massless Dirac, Majorana and Weyl fermions.

Matter particles

Matter particles, also called fermions, are the elementary components of the universe.

a class of elementary particles that includes electrons, protons, neutrons, and quarks, all of which make up the building blocks of matter

In particle physics, fermions are a class of elementary particles that includes electrons, protons, neutrons, and quarks, all of which make up the building blocks of matter.

subatomic particles, reminiscent of nucleons () protons and neutronswhich have half-integral spin

Fermions are subatomic particles, reminiscent of nucleons (protons and neutrons) which have half-integral spin.

particles like electrons and quarks – the building blocks of the matter that we are made of

Fermions are particles like electrons and quarks—the building blocks of the matter that we are made of.

Particles with half-integer spins, 1/2, 3/2, 5/2, ...,

Particles with half-integer spins, 1/2, 3/2, 5/2, ..., are → fermions.

Particles with antisymmetric wave functions

Particles with antisymmetric wave functions are called Fermions and are described by the Fermi–Dirac statistics.

particles that obey Fermi–Dirac statistics

In particle physics, fermions are particles that obey Fermi–Dirac statistics.

the matter and antimatter particles which include quarks, leptons, antiquarks, and antileptons

The fermions are the matter and antimatter particles which include quarks, leptons, antiquarks, and antileptons.

particles that obey the exclusion principle

After Dirac, particles that obey the exclusion principle are today called "fermions", while those that do not are called "bosons".

an electron

For example, an electron is a fermion, while a photon or a helium atom is a boson.

elementary particles whose spin, a quantum property related to rotation

Fermions are elementary particles whose spin, a quantum property related to rotation, is expressed in odd multiples of the fraction 1/2, and they include both quarks and leptons.

elementary particles whose spin – a quantum property related to rotation – is expressed in odd multiples of the fraction 1/2

The fermions are elementary particles whose spin – a quantum property related to rotation – is expressed in odd multiples of the fraction 1/2, and they include both quarks and leptons.

subatomic particles that take up space

Fermions are subatomic particles that take up space, have mass, and constitute the matter in the universe.

the elementary particles that are designated with the odd half-integral spin

Fermions are the elementary particles that are designated with the odd half-integral spin and they are further classified into leptons and hadrons.

even more elemental particles that include quarks and leptons (which include another subparticle, electrons)

Fermions are even more elemental particles that include quarks and leptons (which include another subparticle, electrons).
