    I've been looking on google and my A level physics textbooks but I can't find a clear answer for what I am looking for, can anyone explain to me what the baryon and lepton number of a proton, neutron, beta +, beta -, neutrino and antineutrino are?

    First of all do you know what a baryon and what a lepton is?

    Baryons are made up of 3 quarks whereas leptons are not made up of any quarks. Can you determine the baryon and lepton number of each of those particles now?

    Ok thankyou that helps a lot, but what about antiparticles?

    are there any negative baryon or lepton numbers?

    Yes, antiparticles such as a positron will have a -1 lepton number. Think of them as complete opposites.
