Question

Assume the fission products include three neutrons and Y-102.

The number of protons and neutrons before and after the reaction will agree, as required. Yttrium (Y) has atomic number 39. Iodine's is 55. That adds up to 92, the atomic number of U.

Put that all together in a reaction.

Iodine's atomic number is 53. The rest of the answer is OK as written
