fermions
Half-integer spin particles
Fermions are subatomic particles that follow the Pauli exclusion principle, meaning no two identical fermions can occupy the same quantum state simultaneously.
This category includes electrons, protons, neutrons, and quarks—the building blocks of ordinary matter.
Fermions are distinguished from bosons, which can share quantum states freely.
The term honors physicist Enrico Fermi, who developed the statistical rules governing their behavior.
