Answer:
See the attached worksheet.
Step-by-step explanation:
The attached file explains the the radioactive decay reactions shown in the figure. There are a variety of nuclear decay routes: alphs, beta, gamma, and electron capture are the more common. Conservation of matter apples to these decay reactions. The mass of the particles produced will equal the starting mass. The loss of a proton from a nucleus changes the element: Elements are defined by the number of protons in their nucleus, regardless of their heritage.
