Step 1: Classification of particles
Elementary particles are broadly classified into leptons, quarks, and hadrons. Leptons are fundamental particles that do not experience strong nuclear interaction.
Step 2: Nature of neutrinos
Neutrinos are fundamental leptons. They have zero charge and interact only via weak force and gravity.
Step 3: Nature of neutrons
Neutrons are composite particles made up of quarks (udd). They belong to the baryon family of hadrons and participate in strong interactions.
Final Conclusion:
Thus, neutrinos are leptons, while neutrons are baryons (hadrons), not leptons.
