In fission, a ________ _________ is one where a neutron imbeds itself in the nucleus of a U-235 atom causing it to break apart. After destructing, more neutrons are created. These neutrons can carry on the cycle by finding more U-235, and, again, starting the fissioning process.

Respuesta :

Answer: fisile atom

Explanation:

Nuclear fission is the reaction in which the nucleus of a heavy atom (U-235 atom for example), when bombarded with neutrons (or when capturing an incident neutron), becomes unstable and divides into two or more nuclei of lighter atoms, giving rise to a situation of greater stability. In this process that takes place in the atomic nucleus, neutrons, gamma rays and large amounts of energy are emitted. Ā 

In addition, several neutrons are produced that affect other fissile nuclei,and trigger more fission reactions that in turn generate more neutrons. Effect known as chain reaction.

Chain Reaction
