Nuclear reactor
There is evidence that it did occur on earth some two billion years ago, in a few places with high levels of uranium present. As far as the rest of the Universe, we just don't know.
It would become an atom of a different element. This can only happen during radioactive decay, nuclear fusion, or nuclear fission.
Fission products are the fragments resulting from the fission of heavy nuclids during nuclear fission process
nuclear fission
To sustain a fission chain reaction, each fission reaction must result in one more fission reaction. And that one should result in one more, and so on.
Fission
Fission and fussion manly occar in a star or a sun. The reason that a star or a sun is bright is because of the heat that is given off of from fission and fussion.
The nucleus splits into two parts, which are called the fission products. Free neutrons are also released, and some gamma radiation.
The neutrons produced by fission in a nuclear fission reactor during the process of thermalization to be available for a new generation of fission could be subject to:absorption in fuelabsorption in non fuel reactor components (moderator, clad, structural material, ...)fast leakageresonance capture in U-238fast fission in U-238thermal leakage
The daughter cells may or may not separate
Fission is a nuclear reaction where the nucleus of an atom splits into two or more smaller nuclei, along with the release of a large amount of energy and more neutrons. This process is triggered by bombarding the atom with a neutron, causing it to become unstable and break apart. Fission is the principle behind nuclear power plants and nuclear weapons.
Radioactive disintegration or spontaneous fission
You get nuclear fission in:nuclear fission reactorsatomic fission bombs
Yes, all natural radiation (in the rocks) is a result of fission (but this fission is not part of a chain reaction like in a fission bomb). However, it is theoretically possible for natural processes to concentrate radioactive elements (uranium) to the extent where a natural nuclear fission reactor (a chain reaction like in a nuclear power plant) will form. Oklo in in Gabon is the only known location for this to have happened and consists of 16 sites at which self-sustaining nuclear fission reactions took place approximately 1.7 billion years ago.

The Sun gets its energy from fusion, not from fission. Ocassionaly an atom of a heavier element might go through fission, but that's hardly relevant for the working of the Sun.The Sun gets its energy from fusion, not from fission.

A criticality event, and high risk of loss of life and property.
