3. A sample of the radioactive isotope cadmium-109 is initially 220.0 grams. Use Appendix A from the book for data necessary for this problem. a) How many neutrons are there in a single nucleus of cadmium-109? b) Identify the type of radioactive decay process that cadmium-109 undergoes and write the nuclear decay equation for it. What is the activity of the sample of cadmium-109 one year later, in units of decays per second?
