How can a sample of uranium-235 that has critical mass be induced to react in a controlled nuclear fission reaction?
To induce a controlled nuclear fission reaction in a sample of uranium-235 with critical mass, the sample needs to be bombarded with neutrons. This process, known as neutron bombardment, triggers the splitting of uranium-235 atoms, releasing energy and more neutrons to sustain the chain reaction. By controlling the rate of neutron bombardment, scientists can regulate the fission process and harness the released energy for various applications, such as generating electricity in nuclear power plants.
What are the characteristics and applications of fast neutron energy?
Fast neutron energy is characterized by high kinetic energy levels, making them effective for inducing nuclear reactions. These reactions can be utilized in nuclear power generation, nuclear weapons, and neutron imaging techniques. Fast neutron reactors can also help reduce nuclear waste and increase fuel efficiency in the nuclear industry.
How is plutonium made?
Plutonium is made by the activation of uranium by neutrons. A shaped amount of refined uranium is lowered into an operating nuclear reactor, and the sample is bathed in the neutron flux of the operating reactor. Uranium atoms capture a neutron (via neutron absorption) and transform into plutonium.There are several ways to create plutonium. One is neutron absorption of uranium, followed by two stages of beta decay ...92238U + 01N --> 92239U --> Beta- --> 93239Np --> Beta- --> 94239Pu... leaving out the electrons and the electron antineutrinos.Another way is deuteron bombardment ...92238U + 12D --> 93238Np --> Beta- --> 94238Pu... again, leaving out the electrons and the electron antineutrinos.
How is californium used in nuclear reactors?
We might use californium as a neutron source in a nuclear reactor. Californium is a neutron emitter, and it can be used to "enhance" start-up abilities of a reactor where the fuel isn't as "good" as it might be in a core of, say, highly enriched uranium.
How does the use of a neutron reflector enhance the efficiency of a nuclear reactor?
A neutron reflector enhances the efficiency of a nuclear reactor by reflecting neutrons back into the reactor core, increasing the likelihood of nuclear reactions and the production of energy. This helps sustain the chain reaction and improve the overall performance of the reactor.
How do you make an atom into a different element?
This will happen naturally if the element is radioactive and can be done artificially by means of neutron bombardment in a nuclear reactor or in the heart of a star.

What subatomic particle was discovered second?
The neutron was the second subatomic particle to be discovered, following the electron. It was discovered by James Chadwick in 1932 during experiments involving the bombardment of beryllium with alpha particles. The discovery of the neutron was crucial in our understanding of atomic structure and the development of nuclear physics.
In a nuclear fission reaction a freely moving neutron?
In a nuclear fission reaction, a freely moving neutron undergoes neutron capture and initiates the nuclear fission of a fuel atom.
What happens when you-235 undergoes fission?
When U-235 undergoes fission, it absorbs a neutron and then splits into two smaller nuclei, along with releasing energy, additional neutrons, and gamma rays. This process is triggered by the bombardment of neutrons and is the basis of nuclear power generation and nuclear weapons.
What is a neutron give it uses?
Neutron is an elementary particle, with a mass of approx. 1 amu; neutron is neutral. Neutrons are components of the atomic nucleus; neutrons contain quarks and gluons. Some applications: - neutron radiography - neutron diffraction - neutrons are involved in many important nuclear reactions as reactants or products - the nuclear fission is a problem of neutrons (nuclear reactors, nuclear weapons) - neutron activation analysis - neutron probes for water - experiments in nuclear physics

What is a White radioactive metallic element artificially produced by neutron bombardment of plutonium?
The element you are referring to is californium (CF). It is a highly radioactive metallic element with a white color that is produced by bombarding plutonium with neutrons in a nuclear reactor. Califrornium is primarily used in scientific research and in some industrial applications, such as in neutron moisture gauges and as a neutron source for research purposes.
What are the importance of the element californium?
The isotope 252Cf is a very strong neutron source; some applications are: - neutron's detectors for water and petroleum - control of nuclear fuel rods - treatment of some cancers by neutron irradiation - neutron radiography in industry - neutron activation analysis in mobile installations
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
