In a fission chain reaction, a neutron collides with a uranium nucleus, causing it to split into two smaller nuclei, along with releasing energy and more neutrons. These neutrons then go on to initiate further fission reactions in a self-sustaining chain. In fusion, two light nuclei combine to form a heavier nucleus, releasing a large amount of energy. The released energy can initiate further fusion reactions, leading to a self-sustaining fusion chain.

What is a particle released during the fission of uranium235?
One of the particles released during the fission of uranium-235 is a neutron. When uranium-235 undergoes fission, it splits into two smaller atoms along with several neutrons. These neutrons can then go on to initiate additional fission reactions in a chain reaction.
As the number of neutrons emitted during a fission reaction increases the intensity of the fission process does what?
The number of neutrons emitted during a fission reaction is characteristic of the isotope doing the fissioning, usually U-235 or Pu-239. It does not vary with any ambient condition like temperature or pressure, as it is determined by the properties of the nucleus. What you are thinking of, I believe, is the number of fissions occurring per second in a reactor. Each fission releases a fixed amount of energy, so the total number of fissions per second represents the power level of the reactor.
What type of particle is captured by a nucleus during a fission reaction?
The nucleus splits to form two or more smaller nuclei.
What property of the fission reaction leads to the possibility of a chain reaction?
The fact that when a fission occurs, more than one neutron is released. Thus by careful design, one of these second generation neutrons can be captured by a further nucleus causing another fission, and so on. Up to about 2.5 neutrons per fission can be utilized. In a bomb, all of them are used, and the reactivity (approximately) doubles with each reaction. In a controlled reaction, such as in a reactor, the moderator and geometry are such that one neutron per fission goes on to create another fission, yielding a stable reactivity.
During nuclear fission, mass is converted into what?
During nuclear fission, mass is converted into energy.
Which describes what happens during a chain reaction?
Neutrons released during a fission reaction trigger other fission reactions.
What is needed to produce different isotopes during fission?
The fission reaction must be possible.
Which statements best describes what happens during a chemical reaction?
Chemical bonds are broken and new ones are formed
What products are given off during a typical nuclear fission reaction?
During a nuclear fission reaction, products such as two or more lighter nuclei, neutrons, gamma rays, and energy are given off. These products can vary depending on the specific isotopes involved in the reaction.
How many neutrons are produced during a typical uranium fission reaction and what is the role of these neutrons in a nuclear chain reaction?
A typical uranium fission event produces 2 to 3 neutrons. These neutrons are moderated (slowed down) and go on to initiate the fission of more uranium. On average, in a controlled reaction that is maintained at normal criticality (KEffective = 1), each fission creates exactly one neutron that is used to produce another fission.
What is a particle released during the fission of uranium235?
One of the particles released during the fission of uranium-235 is a neutron. When uranium-235 undergoes fission, it splits into two smaller atoms along with several neutrons. These neutrons can then go on to initiate additional fission reactions in a chain reaction.
What is the only thing that can get changed in a balancing equation?
It is the mass defect during a fission reaction. Enrgy evolved during a radioactive fission can be calculated using the formula gived by Einstein e =mc
Why you use moderators in a nuclear reaction chamber during a fission chain reaction?
A moderator in a fission chain reaction is a system (usually water) that slows neutrons down (decreases their energy) to the point where they can interact with fissile material, causing the fission reaction to be self sustaining. This is necessary because, without the moderator, the neutrons emitted from fission have too much energy to cause subsequent fission. The design of the moderator is such that it provides automatic control of the reaction. As it heats up, the moderation effect decreases, causing the reaction to decrease. Conversely, as it cools down, the moderation effect increases, causing the reaction to increase. In the event that the moderator fails, such as when a depressurization event causes the water to flash to steam, the loss of moderation causes the fission reaction to stop.

What happens during fission when a neutron combines with a uranium-235 atom?
When a neutron combines with a uranium-235 atom, it becomes unstable and splits into two smaller atoms (fission). This process releases more neutrons and a significant amount of energy in the form of heat. These released neutrons can go on to split other uranium-235 atoms, leading to a chain reaction.
What happens to the loss mass during fission?
It becomes energy, hence the energy released in nuclear bombs.
