Radioactive isotopes have unstable nuclei that slowly break apart over time. As they decay, bits of the nucleus (protons and neutrons) are emitted which can cause damage to substances and organisms that are struck by these particles. The simplest type of radiation is the Alpha particle, which is emitted by all elements whose atomic number is 84 or greater. 1. If each alpha particle has the same composition as the nucleus of a Helium atom, how many protons and neutrons...

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...
