Write the isotope needed, by identifying a, z, and x, to balance the following nuclear fission reaction: 23592u+10n→14056ba+azx+3 10n

The nuclear fission reaction is
²³⁵₉₂U + ¹₀n → ¹⁴⁰₅₆Ba + ᵃzX + 3 ¹₀ n

First we must balance all the protons:
92 + 0 = 56 + z + 3(0)
z = 36

Next, we balance the nucleons (protons and neutrons)
235 + 1 = 140 + a + 3*1
a = 91

An atomic number of 36 is Krypton so, X is ⁹¹₃₆Kr.

Answer/// he concludes that the atom particles can be broken due to the paddle wheel being moved by particles coming out of the metal;
