Starting with 235U, assume the following sequence of decays occur:
 
  (1 ) alpha decay
  (2 ) beta minus decay
  (3 ) alpha decay
 
  Determine the correct isotopic product after each process has occurred sequentially.

Question 2

A Carbon-14 nucleus decays to a Nitrogen-14 nucleus by beta decay. How much energy (in MeV) is released if Carbon-14 has a mass of 14.003074 u and Nitrogen-14 has a mass of 14.003242 u?
 
  What will be an ideal response?
