  • 1.Alpha,beta and gamma decay equations

2. Alpha decay is the emission of 2 protons and 2 neutrons from the nucleus Can be represented by Helium 3. Mass number falls by 4 and atomic number falls by 2 4. The LHS and RHS of the equations must balance 5. Beta is an electrons being ejected from the nucleus 6. For this to happen a neutron changes into a proton 7. Mass number stays the same but atomic number increases by 1 8. Gamma is just surplus energy 9. Gamma emission makes no change to the atomic number or mass number
