What else can I help you with?
What products do you gain by nuclear fission?
The products of nuclear fission are typically two or more smaller nuclei, along with the release of energy in the form of gamma radiation and kinetic energy of the fission fragments. Fission of a heavy nucleus can also produce neutrons, which can go on to induce further fission reactions in a chain reaction.
How is it possible to induce a nuclear reaction?
Not by chemical means. A nuclear reaction can be induced by bombarding the nucleus with neutrons, alpha particles, beta particles, gamma rays, high velocity nuclei from a particle accelerator, or cosmic ray particles. Neutrons are most effective at causing nuclear reactions as they have no charge and are reasonably massive.
What is repeated nuclear fission called?
Repeated nuclear fission is called a nuclear chain reaction. In this process, the fission of one nucleus releases neutrons, which can then induce fission in nearby nuclei, leading to a self-sustaining series of reactions. This principle is utilized in nuclear reactors and atomic bombs, where controlled or uncontrolled chain reactions can occur, respectively. The efficiency and safety of such reactions are critical in their applications.
What is the raw material of nuclear fission?
The raw material for nuclear fission is typically a heavy radioactive element, such as uranium-235 or plutonium-239. These materials are bombarded by neutrons to induce a fission reaction, releasing energy in the form of heat and additional neutrons.
When uranium undergoes spontaneous nuclear fission it can?
When uranium undergoes spontaneous nuclear fission, it splits into smaller nuclei, releasing a significant amount of energy in the process. This fission also produces additional neutrons, which can induce further fission events in nearby uranium nuclei, potentially leading to a chain reaction. The byproducts of fission include various isotopes and radiation, which can be harnessed for energy in nuclear reactors or can contribute to nuclear weapons. Overall, spontaneous fission is a key process in both energy generation and nuclear physics research.
Nuclear fuels are bombarded by what particles to induce their fission?

What is fission cross section in nuclear reactor?
The fission cross section in a nuclear reactor is a measure of the probability that a neutron will induce fission in a particular nucleus. It is a crucial parameter for determining the neutron flux and reaction rates within the reactor core. Different isotopes have different fission cross sections depending on their ability to undergo fission when struck by a neutron.
What is spilt during a nuclear fission?
During nuclear fission, the nucleus of an atom splits into two or more smaller nuclei, along with the release of a significant amount of energy. This process also produces free neutrons and gamma radiation. The released neutrons can further induce fission in nearby nuclei, leading to a chain reaction. Commonly, uranium-235 and plutonium-239 are used as fuel in fission reactions.
Why were Hahn and Meitner bombarding nuclei with neutrons in the first place?
Hahn and Meitner were bombarding nuclei with neutrons to induce nuclear reactions, hoping to create new elements and understand nuclear structures. This technique allowed them to study the process of nuclear fission, which eventually led to the discovery of nuclear energy and the development of nuclear weapons.
Is heat required to change one element into another?
Yes, heat can be required to change one element into another through processes like nuclear fusion or nuclear fission. These processes involve high temperatures to induce the necessary reactions for transformation.
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.
In nature one element can change to another by what process?
Transmutation is the process by which one element changes into another. This can only be done with a nuclear reaction, but alchemists once believed it might be possible, for example, to transmute lead into gold. They tried many bizarre things, but were never successful. Only nuclear reactions, such as fusion, fission, radioactive decay, etc, can induce a transmutation
