Spontaneous fission is a naturally occurring nuclear decay event that a few different elements undergo. Uranium and plutonium, which are radioactive, are the most well known of the fissionable elements, and they can do this in nature. The nucleus of the atoms of these elements are naturally unstable, and they can just "split" by themselves. The instability is a characteristic of these and some other elements, and this is because these large nuclei are so massive that their nuclear binding energy cannot hold them together indefinitely. Note that spontaneous fission is just one possibility as regards the decay of these heavy nuclei.
In spontaneous fission, the unstable nucleus just falls or breaks apart by itself. The nucleus splits in two parts of approximately the same size, and these are the fission fragments from the decay event. One or more neutrons will be released at this time, too. The fission fragments recoil with a great deal of kinetic energy. Further, it is spontaneous fission that begins all nuclear chain reactions in nuclear weapons and in nuclear reactors. A link can be found below for more information.

What is the difference between induced fission and spontaneous fission?
Spontaneous Fission is the process of Elements and Induced Fission is the process of firing neutrons at heavy Atoms
Would it be a good idea to build a nuclear power reactor the utilized spontaneous fission why or why not?
No. For 2 main reasons: 1) In a fission reaction the atoms split. Consequently, radioactive waste will be produced ( which is very expensive to store and keep them). 2) It will take billions of years for it to decay.
How does fission happen?
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.
What causes a splitting nucleus?
The capture of a neutron can split a nucleus - but only for certain isotopes like U-235 and Pu-239. Two naturally occurring isotopes undergo spontaneous fission, meaning the nucleus splits without neutron capture. These are 235U and 238U. A few other isotopes undergo spontaneous fission, but these are produced by an earlier neutron capture. Spontaneous fission is the result of quantum tunnelling, which is rather difficult to explain. There are related links below.
How can nuclear changes occur?
Nuclear changes can occur through processes such as fission, fusion, and decay. Fission involves splitting heavy nuclei into smaller ones, releasing energy. Fusion combines light nuclei to form heavier ones, also releasing energy. Decay involves the spontaneous transformation of unstable nuclei into more stable ones, emitting radiation in the process.

How does spontaneous fission or an ionization chain reaction finally reach a stable configuration?
When it runs out of material.
Would it be a good idea to build a nuclear power reactor that utilized spontaneous fission?
maybe
What particle is used to start nuclear fission?
In actuality, a spontaneous fission event begins a nuclear chain reaction. It kick starts a nuclear chain reaction. And a neutron from that fission will initiate another fission to continue and rev up that nuclear chain reaction.
What type of radiation is released during the decay of californium?
Alpha particles and neutrons fron spontaneous fission

No. For 2 main reasons: 1) In a fission reaction the atoms split. Consequently, radioactive waste will be produced ( which is very expensive to store and keep them). 2) It will take billions of years for it to decay.
What is likely to happen to atoms like plutonium with many neutrons and a heavy nucleus?
Radioactive disintegration or spontaneous fission
What were the rays emanating from uranium?
* Alpha rays (particles) * Beta rays * Gamma rays * Spontaneous fission neutrons
What radioactivity is einsteinium in?
Einsteinium isotopes can emit alpha particles, beta particles, positrons; spontaneous fission is also possible.
What are the harmful rays radiated from uranium?
Principally alpha particles, but also gamma rays, neutrons from the spontaneous fission, etc.
Spontaneous nuclear fission processes occur by?
Spontaneous nuclear fission processes occur when the nucleus of an atom undergoes a process where it splits into two or more smaller nuclei. This process releases a large amount of energy along with neutrons and is typically associated with heavy isotopes like uranium or plutonium. The fission process is initiated by the absorption of a neutron by the nucleus, leading to instability and eventual splitting.
What is induced nuclear fission?
We might think of induced nuclear fission as a fission reaction that occurs when a neutron is captured by, say, a uranium-235 atom and that atomic nucleus undergoes fission as a result. Most all of the fission events within a nuclear reactor or nuclear weapon are induced. Given this, we might then compare that fission event to a spontaneous fission event wherein the atomic nucleus of a uranium-235 atom spontaneously undergoes fission without having captured a neutron.
