How is the number of neutrons in an assembly involved in creating a sustained nuclear chain reaction?
This answer can not be accurately answered without first knowing what type of nuclear reactor it is. A pressurized-water nuclear reactor is probably the most common so I'll briefly talk about some factors that affect the number of chain reactions in that type of nuclear reactor. First of all, the temperature of the water entering the reactor core will affect the number of chain reactions. The colder the water, the greater the number of reactions. This is primarily because the colder water is more dense and thus releases more neutrons which speeds up the chain reaction rate. Of course, reactor operators, wishing to control the number of chain reactions in order to make the reactor stable may raise or lower "rods" which will be made of a material that tends to absorb neutrons and thus lowering the chain reaction rate. These are the two most common factors affecting chain reaction rate. Would delve further into this question but it gets rather complicated at this point.

How is a fission reaction initiated and sustained?
A fission reaction is initiated by bombarding a heavy atomic nucleus, like uranium or plutonium, with a neutron. This causes the nucleus to split into two smaller nuclei, releasing more neutrons and a large amount of energy. To sustain the reaction, these released neutrons must continue to collide with other nuclei, causing them to split and release more neutrons, creating a chain reaction. This process is carefully controlled in nuclear reactors to generate heat for electricity production.
How does a nuclear reactor shoot neutrons?
In a nuclear reactor, the fission process splits heavy atomic nuclei, releasing energy and additional neutrons. These neutrons can then collide with other nuclei, causing them to split and release more neutrons, creating a self-sustaining chain reaction. Controlling the number of neutrons and their interactions is crucial to the operation and safety of a nuclear reactor.
Do neutrons decay, and if so, what is the process involved in their decay?
Yes, neutrons can decay. Neutron decay is a process where a neutron transforms into a proton, an electron, and an antineutrino. This process is known as beta decay.
What happens in a nuclear chain reaction and how does it contribute to the release of energy in a nuclear reactor?
In a nuclear chain reaction, the splitting of atomic nuclei releases energy in the form of heat. This process is controlled in a nuclear reactor to generate electricity. The chain reaction is sustained by the release of neutrons from the splitting of nuclei, which then go on to split more nuclei, creating a continuous cycle of energy release.
What is the function of graphite in a nuclear reactor?
Graphite is used as a moderator in nuclear reactors to slow down neutrons produced during nuclear fission. Slower neutrons are more likely to cause additional fission reactions, allowing for a sustained nuclear reaction. Graphite is also used as a structural material in some reactor designs.
Why don't we care about neutrons in chemistry?
Neutrons are not involved in chemical reactions.
What is an assembly of protons and neutrons within an atom called?
An assembly of protons and neutrons within an atom is called a nucleus. It is the central part of an atom that contains most of the mass of the atom and is positively charged due to the protons it contains.
When a moose smells a leafy plant what kind of neutrons are involved What roles do the neutrons serve?
rat
What part of a fission reaction makes is capable of producing energy from a self sustained chain reaction?
You think probable to neutrons.
Which particles that make up an atom are involved in nuclear reactions?
Protons, electrons, and neutrons are the subatomic particles that are involved in nuclear reactions.
What particles are involved in nuclear reactions but not in chemical reactions?
Neutrons and protons are involved in nuclear reactions because they reside in the nucleus of an atom. In contrast, electrons are involved in chemical reactions as they participate in forming chemical bonds between atoms.

What are three kinds of neutrons that would be involved in a reflex impulse?
They are neurons and not neutrons. You have afferent neuron. Then you have intermediate neuron and then you have the efferent neuron in the reflex arc.

Describe a characteristic of a fissionable substance that is essential for a chain-reaction to sustain itself?
The fission process is sustained by neutrons. A neutron entering a nucleus and causing fission must be replaced in order to cause the next fission, and so on. So the fissionable substance must emit more neutrons when fission occurs, and enough of them so that despite some being absorbed by the moderator and some leaking from the reactor boundary, there is still enough to maintain the chain reaction. Uranium 235 emits on average about 2.5 neutrons per fission (you might say what is half a neutron, but this is explained by the fact that fissions have a range of possible results, with different numbers of neutrons emitted, and the average is 2.5).
What are the two particles involved in the atomic mass of an element?
