Only certain elements are fissionable, or at least with practical means. The fission of for example the atom U235 happens when it is struck by a slow neutron, it splits, which is fission, releasing two smaller atoms and two or three neutrons (products). The products from the nuclear reaction weigh less then the original atoms. The difference in weight is converted into energy.

What is fission product?
Fission products are the fragments resulting from the fission of heavy nuclids during nuclear fission process
What is the splitting of an atoms nucleus into two smaller nuclei is called?
nuclear fission
What causes the atom's nucleus to split?
- for spontaneous fission the cause is an inconvenient ratio between neutrons and protons- bombardment of the nucleus with particles, especially neutrons
Are all fission events in a chain reaction identical?
Nuclear event in a chain reaction could be said to be similar, but not identical. We need to look a bit more closely at a fission event to understand why. In a fission event in a chain reaction, a neutron is absorbed by a fissile nucleus, and the resulting instability causes that nucleus to fission, or split. When the nucleus splits, it splits into two approximately parts (called fission fragments), but not the same two parts will appear in every fission event. And one, two or three neutrons might appear, depending on exactly which two fission fragments appear. The total energies in the events will vary from event to event as well, and this has something to do with the energy the absorbed neutron brings when it is absorbed. We know fission events are similar, but there are variations that preclude them being identical.
If For a sustainable fission reaction each fission must produce exactly how many additional fission reaction(s).?
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.
What causes water change to vapor?
the evaporation causes nuclear fission which therefore causes the object c341o to become C12a.
What causes lesser pollution - nuclear fission or fusion?
Nuclear fusion
What are the causes of blast?
A large release of energy from atomic nuclei, either via fission or fusion.
What are the causes of bomb blast?
A large release of energy from atomic nuclei, either via fission or fusion.
What is a chemical chain reactionA chemical reaction that causes the next one.(for geoscience Nuclear fission and fusion)?
Share A chemical reaction that causes the next one
What are the causes of nuclear bomb blast?
A large release of energy from atomic nuclei, either via fission or fusion.
What is the nuclear transformation of atoms?
There are several types of nuclear transformation:Alpha decay causes the ejection of a Helium Nucleus.Beta decay causes the ejection of an electron and a neutrino while one neutron in the nucleus becomes a proton.Gamma decay causes the ejection of a very high energy photon.Fission causes a massive nucleus to split into two smaller ones, usually about 1/3s and 2/3s the mass of the original nucleus, and a few neutrons. Some isotopes of elements that fission can fission spontaneously, some can't. In those isotopes that can't fission spontaneously, fission is triggered by neutron capture.Fusion causes light nuclei to merge into heavier ones. This only happens at very high temperature and pressure.Capture causes a nucleus to absorb another particle, usually a neutron, and transmute into a different isotope or element. Capture is usually followed by one of the types of decay.
Where do you get nuclear fission?
You get nuclear fission in:nuclear fission reactorsatomic fission bombs
What are the causes of a nuclear explosion?
Sudden release (in a few microseconds) of nuclear energy via fission, fusion, or a combination of both.
What causes heat and light in stars?
The heat and the light in stars is the same thermal nuclear fission that our Sun (a star) produces.
What have chain reactions got to do with nuclear fission?
The fission process in a nuclear reactor which produces the thermal energy used in the steam cycle, is called a chain reaction because nuclei of U-235 and Pu-239 fission on absorbing a neutron, and the fission causes further neutrons to be released, thus a self sustaining reaction is started which is controlled to run at a steady power level.
Where does the small amount of technetium from the earth come from?
Two causes are possible: - spontaneous fission of uranium - a reaction (n, gamma) of molybdenum
