Compare and contrast the decay processes of electron capture and positron decay by answering the following questions: State two similarities and two differences. Include the changes in characteristics of the element including protons, neutrons, and electrons, type of transition and emissions. You may include a drawing on your math work pages to aid in demonstrating your answer. 

Answer the following questions about isomeric transition: What is the emission from an isomeric transition? What alternative process can occur instead of an isomeric transition? What emissions result from the alternative decay process? Given a pair of radionuclides such as Tc-99m and Tc-99, which one can undergo isomeric transition, and what radionuclide will result from this decay?
