What does fission happen in?
Nuclear reactor
Where nuclear fission is found?
In a nuclear power plant and in nature in (low levels.) With any form of radioactive decay it is possible for atoms to be split. The sustained reaction is the foundation of both nuclear weapons and nuclear power plants where the fission is self-sustaining for a period of time. A simple physical model is a pool (billard) table when you initally break. The cue ball is a small particle that breaks up the racked balls. Now imagine hundreds if not millions of other racked balls. A chain reaction of breaks continues until there isn't enough energy to stustain the fission of atoms. Low levels of this happen all the time with radioactive material in nature. Once there is a "critical mass" of very specific radioactive material a sustained chain reaction happens. Controlled you can get nuclear power by siphoning the reaction in the form of heat to turn turbines for power, let it all go at once and you get a nuclear bomb. Fission is the splitting of atoms, fusion is merging atoms. A hydrogen bomb uses both fission and fusion. Fission to start the reaction (Plutonium) and an outer shell that (Cesium,cobalt, if memory serves me correctly were two material used for the outer casing), from the force of the fission, causes the fusion of hyrodgen (hence H-Bomb).
In a nuclear fission reaction a freely moving neutron is introduced to a nuclear fuel such as uranium-235. What happens next?
a neutron is absorbed by an atom’s nucleus. (apex)
What are negative aspects of nuclear fission?
Negative aspects of nuclear fission include the generation of radioactive waste that requires long-term storage, the risk of accidents leading to releases of radioactive materials, and the potential for nuclear proliferation if the technology falls into the wrong hands. Additionally, the cost of building and maintaining nuclear power plants can be prohibitive.
Atoms that naturally undergo nuclear fissions are called?
These are called fissile or fissionable. Fissile isotopes undergo fission, producing sufficient neutrons of sufficient power that a chain reaction can happen, if there is enough of the isotope to support it. The mass sufficient to support a chain reaction is called critical. Atoms of fissionable isotopes will undergo fission when a sufficiently energetic neutron collides with them, but the neutrons they emit when they divide are either insufficient in number or insufficient in energy to sustain an chain reaction. There is a third type of material that can undergo fission, called fertile, which is isotopes that can be caused to capture neutrons, changing into fissile or fissionable isotopes, so the fission does not happen to atoms of the fertile material directly, but to the atoms of the isotopes they become.

What would happen to a nuclear plant if the fission reaction goes critical or out of control?
There are emergency safety system that could be used to bring the nuclear plant again under control.
Can fission happen on earth?
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.
Can fission take place in the nucleus of hydrogen atom?
No, it cannot. Fission is the "splitting" of an atom, and a hydrogen atom will not fission. Some hydrogen atoms have a neutron stuck to the proton in their nucleus. Some even have two neutrons stuck to that proton. These neutrons can be "knocked loose" in something like a nuclear chair reaction in a weapon. The neutrons then can contribute to the building of the nuclear chain reaction. But fission doesn't happen to hydrogen.
Why do they happen nuclear explosion?
Nuclear explosions happen for many reasons: An uncontrolled chain reaction (fission reaction) occurs with uranium 238, A fission reaction is where 1 large nucleus (centre of an atom) splits up into 2 or more smaller nuclei giving off neutrons. These neutrons then hit another nucleus changing it into smaller nuclei and so on. e.g. (chain reaction) feel free to add some more info...

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.
How can nuclear fission be forced to happen?
by a neutron source. nuclear reactors are always started with one to avoid a supercritical power surge from damaging the reactor. nuclear bombs are always triggered by one to make sure the reaction happens at optimal supercriticality for desired yield.
When and where was the nuclear fission was invented?
See the link below. The answer is it did not happen all at once or in one place, the knowledge evolved over a period of years. The first chain reaction was in the Chicago pile, 1942
