Fermion
Type of subatomic particle
In particle physics, a fermion is a subatomic particle that follows FermiāDirac statistics. Fermions have a half-integer spin (spin ā 1/2ā , spin ā 3/2ā , etc.) and obey the Pauli exclusion principle. These particles include all quarks and leptons and all composite particles made of an odd number of these, such as all baryons and many atoms and...
