Alpha, Beta-plus, Beta-minus and Gamma decay are all different forms of radio-Active decay. A certain radio-isotope emits TWO alpha particles, and its products then emit TWO beta-minus particles in succession. The atomic number of the final resulting nucleus will now change (as compared to your starting nucleus) by
