My answer -
The condition in the nucleus are likely to result in the nucleus
breaking apart is called the nuclear fission. But if it is the atomic
nucleus that is breaking apart, it should be called as the nuclear
fusion. These things usually can be caused by the decay of the
radioactive and the nuclear reaction.
P.S
Happy to help you have an AWESOME!!! day :)
