What are neutron-rich nuclei?
Neutron-rich nuclei could be said to be atomic nuclei that have a large number of neutrons. The term, however, is generally used in conjunction with the physics of nuclear fission, or the nuclear chain reaction. Fission relies on the production of neutrons to build or maintain the chain reaction (depending on the application - reactor or bomb). Neutrons are let loose in nuclear fission. But if some other materials can be included in the construction of the fission device so that they, too, contribute neutrons to help build the chain, then that would be helpful. (That's what the German heavy water project was all about.) Generally, neutron-rich nuclei are atomic nuclei that can contribute, can add to, the number of neutrons available to support a chain reaction.
Describe a characteristic of a fissionable substance that is essential for a chain reaction to sustain itself?
Firstly it must be able to capture neutrons which then have a high probability of causing its nuclei to undergo fission or splitting, and the fissions must produce enough further neutrons so that for every fission that occurs, another one will follow.
How can uranium 235 create electricity?
In physics and nuclear fission. A neutron is fired at a uranium-235 atom which then splits into daughter nuclei, the daughter nuclei releases more netrons which splits more and more uranium-235 atoms. This is called a chain reaction. The chain reaction releases heat which can then be used to turn a turbine which turns a generator and generates electricity. A moderator can be used to slow down neutrons and the chain reaction. When the neutrons are slowed down to the right speed, control/fuel rods absorbs the neutrons which slows down the reaction rate. This makes nuclear fission controllable, unlike nuclear fusion which is uncontrollable. Hope this helps
What is the chemical equation for nuclear fission?
It is not a chemical reaction! You can write U-235, with atomic number 92, plus a neutron, produces two fission product nuclei (which can be various combinations) plus two or three free neutrons. The limitations of notation on this site does not allow to show this properly. If you look up nuclear fission in Wikipedia you will see how such a reaction is written.
How does the uranium and plutonium react in the nuclear reactor?
To set off a fission reaction (the reaction that occurs in a nuclear reactor), a person must first pump a neutron into a heavy nucleus. So if a neutron is pumped into a uranium or plutonium nucleus capable of undergoing fission, the nucleus splits in two, and releases more neutrons, which hit more nuclei, which in turn send out even more neutrons, thus setting off a chain reaction where every time a neutron hits a nucleus, the nucleus splits in two and sends out more neutrons.
Why are neutrons fired at the uranium nuclei?
Under bombardment with thermal neutrons a nuclear fission is produced with the isotopes 235U and 233U; a formidable energy is released after fission.

What is the purpose of control rods in a nuclear reactor?
A nuclear reactor requires the neutrons released from one reaction to trigger the fission of other nuclei. Control rods are required to absorb some of these neutrons so as to prevent a runaway chain reaction.
What is a nuclear explostion?
A nuclear explosion is the uncontrolled reaction (either fusion of fission) of nuclei and nuclei (fusion) or nuclei and neutrons (fission). Both processes produce vast amoutns of energy, as well as more nuclei or neutrons (for fusion or fission, respectively) to continue the chain reaction. This energy, if not moderated (such as in the case of a nuclear reactor, in which this reaction is harnased to produce electricity), explodes with a force many many times that of an equal quantity of dynamite (on the order of tens or even hundreds of thousands of times more force) or other conventional explosives.
What nuclear process is happening during the main sequence?
Nuclear fission. It realeases nuclear energy by spitting big atomic nuclei, usually those of uranium. Neutrons are fired at the nuclei. As the neutrons smash into the nuclei they split off more neutrons, which bombard other nuclei, setting of a chain reaction, which makes energy.
A nuclear reaction in which an atoms nucleus is split into two smaller nuclei and energy is released as heat is known as?
nuclear fission
How does a chain reaction start in chemistry?
In a nuclear fissionchain reaction, neutrons are absorbed by large nuclei, and they undergo fission, part of the fission products are more neutrons, which are absorbed by more nuclei, which ... blah, blah, blah.
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.
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...
An ongoing series of fission reactions is called a (n) .?
Fission and fusion reactions are chain reactions but in different ways. In fission reaction a heavy nuclei is bombarded with a slow moving neutron and this nuclei breaks to produce more such neurons along with generation of new elements. These slow moving neutrons are further used to carry out fission of more such nuclei. This is chain reaction. Fusion reaction are a different class of nuclear reaction in which small nuclei fuse together to produce bigger nuclei along with the generation of energy due to mass defect.. In fusion reaction lot of energy is produced and this energy is used to carry out further reaction. Thus both can be called series reaction.
What nuclei are fused in the nuclear reaction of a hydrogen bomb?
Deuterium (heavy hydrogen) nuclei and tritium nuclei to form helium nuclei. This comes from lithium deuteride in modern "dry" hydrogen bombs. Neutrons from fission splits the lithium generating tritium just before fusion is ignited..
What is splitting of atomic nuclei?
FISSION. nobody on this website knows the answer..... SHAME
