Each of the following particles obeys the Pauli Exclusion Principle except
A) electron.
B) neutron.
C) photon.
D) proton.

Question

Quizplus · Accepted Answer

The Pauli Exclusion Principle applies to fermions, which are particles with half-integer spin. Electrons, neutrons, and protons are all fermions with a spin of 1/2, and thus they obey the Pauli Exclusion Principle. Photons, on the other hand, are bosons with integer spin (spin 1), and do not obey the Pauli Exclusion Principle.
