A nuclear decay is possible if the mass of the parent nucleus exceeds the total mass of the decay particles. If M ( A , Z ) denotes the mass of a single neutral atom of an element with mass number A and atomic number Z, then the minimal condition that the decay X _ Z ^ A Y _ Z +1 ^ A + ⁻+ v _ e will occur is ( m _ e . denotes the mass of the particle and the neutrino mass m _ v can be neglected):

Options

  1. AM(A, Z)> M (A, Z+1)+m_ e
  2. BM(A, Z)>M(A, Z+1)
  3. CM(A, Z)>M(A, Z+1)+Z m_ e
  4. DM(A, Z)>M(A, Z+1)-m_ e

Correct answer

A. M(A, Z)> M (A, Z+1)+m_ e
