Question

Adding one neutron to ²³⁵U results in the excited state ²³⁶U that quickly decays into unstable isotopes of xenon and strontium plus two extra neutrons.

234 U92 + n → 236 U92 → 140 Xe54 + 94 Sr38 +2n

How do the sum of the rest masses in initial and final states compare?

a. sum of the masses of the initial state (²³⁵U₉₂ + n) > sum of the masses of the final state (¹⁴⁰Xe₅₄ + ⁹⁴Sr₃₈ + 2n)

b. sum of the masses of the final state (¹⁴⁰Xe₅₄ + ⁹⁴Sr₃₈ + 2n) > sum of the masses of the masses of the initial state (²³⁵U₉₂ + n)

c. sum of the masses of the final state (¹⁴⁰Xe₅₄ + ⁹⁴Sr₃₈ + 2n) = sum of the masses of the initial state (²³⁵U₉₂ + n)
