Which of the following reactions is(are) possible for isolated decaying particles on the right side, without requiring energy?
The correct options are Bn→p+e+¯v C19O→19F+e+¯v Second and third process are possible.
A) Rest mass energy of neutron is greater than proton. So conversion of p to n is not possible for an isolated proton and requires energy. D) Charge is not conserved. 25Al converts to 25Mg when proton converts to neutron hence correct process will be⇒25Al→25Mg+e++v
