Q.No.23: - What are hadrons and their categories ? Give example.

Ans: - Hadrons are composite particles. Those Baryons and fermions who made up of valence quarks are called hadrons.
                 There are two main types of hadrons are one is Baryons and the other is mesons. Baryons are made up of odd number of valence quarks usually they are 3 valence quarks and mesons are made up of even number of valence quarks usually 2 valence quarks in which one is quark and the other is anti-quark. Protons and neutrons are examples of baryons and pions are examples of mesons.
