A chain reaction results when a uranium atom is struck by an neutron released by a nearby atom?

This is the process involved in nuclear fission in a nuclear power station. The chain reaction is set off when one neutron is fired into the reactor. It hits a uranium atom which then splits into 2 smaller atoms and 2 more neutrons are released that collide with two more atoms and so on...

What is the type of nuclear reaction typically used in power plants?
Uranium FissionU235 or U238 fission by neutron decay.Here is a Wikipedia image showing a Neutron inducing U235 to split into Barium and Krypton, and releasing additional Neutrons.http://en.wikipedia.org/wiki/Nuclear_fissionThis image is from Wikipedia, and was released into the Public Domain by its author, FactFission.
The type of particle a uranium-235 must absorb before it can split?
A neutron
Is uranium 238 a slow or fast neutron absorber?
uranium 238 is a fast neutron absorber the answer is correct but for more explanation:- when uranium 238 is bombard by neutron >>> uranium 238 , undergoes B decay>>>Np 239 ,undergoes B decay >>> Pu 239 finally undergoes alpha decay >>> fissile U
What is a fission nuclear reaction?
The primary result of a fission reaction is the conversion of mass to energy. In fission, the nucleus split, either through radioactive decay or as result of being bombarded by other subatomic particles known as neutrons.
What is the fission of U-235 nuclei initiated by?
initially inside a nuclear reactor, uranium fuel such as uranium 235 is lowered inside the reactor and excess neutron is released, which is then absorbed by the uranium fuel and it atomically becomes unstable, so it splits into two smaller nuclei and more excess neutrons released. Again the same reaction occurs and splitting the nuclei into more smaller nuclei until it dies of or becomes atomically stable, the result of this is chain reaction.
Chain reaction results when a uranium atom is struck by?
Thermal neutrons
How many neutrons are there when uranium 235 is bombarded with a neutron?
Uranium 235 has 143 neutrons; absorbing a neutron (neutron,gamma reaction) the isotope uranium-236 is obtained.
Name the element when uranium captures a fast neutron?
The element is determined by the number of protons. When uranium captures a fast neutron it is still uranium but has an increased atomic mass. Fast neutron capture may encourage a further reaction but it depends on which uranium isotope you start with as to the increase in probability some further reaction will occur and which reaction that might be.
What creates nuclear energy?
Uranium was created in supernova explosions more than 7 billion years ago. The nuclear energy in this uranium is released by nuclear fission of the atomic nuclei in a neutron chain reaction.
When a nucleus absorbs a neutron and then breaks apart there are many products of the reaction Which of these is not a product of a nuclear fission reaction?
Uranium-235
When a nucleus absorbs a neutron and then breaks apart there are many products of the reaction . Which of these is not a product of a nuclear fission reaction?
Uranium-235
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 atoms nucleus
In a nuclear fission reaction a freely moving neutron is introduced to a nuclear fuel such as uranium what happens next?
If things go according to plan, the neutron encounters a fissionable atomic nucleus and then undergoes what is called neutron capture. That's the next step in the process. The presence of that neutron in the nucleus destabilizes the nucleus (more than it already is as that nucleus is radioactive and unstable anyway). In an extremely short period of time the instability results in nuclear fission. The nucleus splits.
Why does only one neutron need to be fired to react all of the uranium 235 atoms?
For each nuclear fission are released approx. 2,5 neutrons and a nuclear chain reaction is initiated.
When uranium 238 is bombarded with a neutron it can change into what?
The nuclear reaction is: 23892U + n-------23992U-------23993Np + e--------23994Pu + e
What are the daughter atoms of uranium-235 during the initial chain reaction?
Fission is a form of nuclear transmutation because the resulting fragments are different elements from the original atom. A neutron-induced fission of U-235 results to krypton and barium.
What happens when a neutron hits a large uranium nucleus?
One thing that can happen when a neutron interacts with a uranium atom is called scattering. The neutron "bounces off" the uranium. Aside from scattering, a neutron has a possibility of being absorbed by the uranium nucleus, and this can cause several different reactions, depending on which isotope of uranium is involved in the reaction. It is neutron absorption that is the mechanism utilized in the chain reactions in nuclear weapons and in nuclear reactors. Nuclear fuel, which is often uranium-235, fissions by absorbing a neutron. In the case of uranium-238, we make plutonium by getting that isotope to absorb a neutron. There is a lot more to learn, and you'll find related links below to get you going.
