         • Mesons
           • Kaon K
           • Pion π
             • +, 0 or -
           • Baryon No. = 0
         • Baryons
           • Proton p
             • Charge = 1.6 ×10^(-19) C Relative Charge = +1 Mass = 1.675 ×10^(-27) kg Relative Mass = 1 Quark Configuration: uud
           • Antibaryons
             • Baryon No. = -1
             • Antiproton p ̅
             • Antineutron n ̅
           • Baryon No. = 1
           • Neutron n
             • Charge = 0 C Relative Charge = +1 Mass = 1.673 ×10^(-27) kg Relative Mass = 1 Quark Configuration: udd
         • All decay into a proton.
           • 11 min Half Life
         • Strong Force Dcay
     • Quarks
   • The Atom
     • Nuclei
   • Photons
   • Radiation
     • Gamma γ
       • Electromagnetic wave. No mass or charge. Emitted when the nucleus has too much energy (E) following α or β decay.
     • Alpha α
       • Helium Nucleus (2p, 2n) The daughter nucleus may be stable or unstable.
     • Beta β
       • High energy electron. During decay, a neutron becomes a proton. The β particle is produced at the point of change and is emitted immediately. It occurs when there are too many neutrons in a nucleus.
       • Beta + Decay
         • u -> d
           • uud -> udd
       • Beta - Decay
         • d -> u
           • udd -> uud
   • Electromagnetic Spectrum
     • E=hf
