... Spin quantum number “s” is a unique property of a particle. Fermions have half integer value of “s”. Two fermions cannot occupy the same quantum state. Electron, Proton, Neutron: s=1/2 Bosons have full integer value of “s”. There is no limitation in the number of bosons that can occupy the same stat ...
