What is a fermion?
Quick Answer
A fermion is a particle with half-integer spin that follows the Pauli exclusion principle. Electrons, protons, and neutrons are fermions.
The Full Story
Fermions are the particle family that makes up matter. Because of the Pauli exclusion principle, two identical fermions cannot occupy the same quantum state at the same time, which is crucial for the structure of atoms and the stability of ordinary matter. Electrons are fermions, as are quarks, which combine to form protons and neutrons. Without fermions, atoms as we know them would not exist.
Key Facts
1.Have half-integer spin
2.Include electrons, quarks, protons, and neutrons
3.Obey the Pauli exclusion principle
