Write a nuclear reaction for the neutron-induced fission of U−235 to produce Te−137 and Zr−97. please help?
When uranium-235 undergoes a neutron-induced fission reaction, it will split into two smaller nuclei, which, in your case, are tellurium-137,
So, you know that the uranium-235 nucleus must collide with a neutron, which is a subatomic paticle that has no electric charge and a mass approximately equal to that of a proton, 1.
Those will be your rectants.
Isotopes are written in the form
#-># #Z = 92#
Now you have what you need to write the nuclear equation.
You can figure out how many neutrons the reaction will release by balancing the mass numbers. On the reactants' side you have 235 + 1, and on the products' side you have 137 + 97 + ?.
This means that
The atomic numbers are already balanced, since you have 92 + 0 on the reactants' side, and 52 + 40 on the products' side.
Therefore, the balanced nuclear equation for this reaction is
