7.19 chain reaction of Uranium 235 nuclei

When a neutron collides with a uranium 235 nucleus it forms uranium 236 which undergoes fission. This fission of U-235 also releases neutrons that can collide with more uranium 235 nuclei if they are around hence triggering them to undergo fission as well. This repeats over and over again forming a chain reaction.
