Respuesta :

A neutron is absorbed by the original uranium-235 nucleus before it splits into two new nuclei, krypton-92 and barium-141, which also releases three additional neutrons. These three neutrons can then split three more uranium-235 nuclei, releasing more neutrons with each fission, and so on.

When does a thermal neutron enter the U-235 nucleus?

A U-235 nucleus splits into two pieces when it takes in an extra neutron. Fission is the name of this process. Two to three neutrons are released each time a U-235 nucleus splits. Consequently, starting a chain reaction is a possibility.

U-235 atoms take in free neutrons during fission. Due to this, U-235 becomes unstable and fragments into two light atoms known as fission products.
