    need help with this. thanks Please answer the following questions by replying: 1. Why is it that during alpha emission, the atomic number decreases by two, and the mass number decreases by four? In your answer you should consider what an alpha particle is. 2. In beta emission, the atom loses an electron, yet the atomic number increase by one and the mass number stays the same. How is this possible? It may help if you consider what happens to...
