1.  The bombardment of fluorine-19 by alpha particles generates sodium-22 and neutrons. Write the nuclear equation for this transmutation, including the intermediate compound nucleus.
 
2. Neutron bombardment of cadmium-115 results in neutron capture and the release of gamma radiation. Write the nuclear equation. 
 
3. If an atom of beryllium-7 decays by the capture of a K-electron, into which isotope does it change? Write the equation.
 
4. What are some "rules of thumb" that can be used to judge if a particular radionuclide might have a long enough half-life to warrant the effort to make it?

11. A radioactive element A with mass number 180 and atomic number 80, emits an alpha particle and changes to element B. Element B emits a beta particle and is converted to element C. Write nuclear equations for these three changes using mass number and atomic numbers of the particle A, B and C. Which of the particles A, B, or C, are isotopes of the same element
