What is the formula of uranium-235 during fission?
During fission of uranium-235, the nucleus of uranium-235 absorbs a neutron and becomes unstable. It then splits into two smaller nuclei (such as barium and krypton), releasing energy and additional neutrons in the process. The formula for this process can be represented as: U-235 + 1 neutron → Ba-141 + Kr-92 + 3 neutrons + energy
When a uranium nucleus breaks into fragments what type of nuclear reaction occurs?
In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei), often producing free neutrons and photons (in the form of gamma rays).
How neutron is bombarded on uranium?
Neutrons are typically bombarded onto uranium-235 nuclei to induce nuclear fission reactions. When a neutron collides with a uranium-235 nucleus, it can be absorbed, causing the nucleus to become unstable and split into two smaller nuclei, along with releasing more neutrons and a large amount of energy. This process is the basis of nuclear power generation and nuclear weapons.
What is the process called that releases energy from Uranium?
The process is called nuclear fission, where the nucleus of a uranium atom is split into smaller nuclei, releasing a large amount of energy in the form of heat and radiation.
How does the uranium and plutonium react in the nuclear reactor?
To set off a fission reaction (the reaction that occurs in a nuclear reactor), a person must first pump a neutron into a heavy nucleus. So if a neutron is pumped into a uranium or plutonium nucleus capable of undergoing fission, the nucleus splits in two, and releases more neutrons, which hit more nuclei, which in turn send out even more neutrons, thus setting off a chain reaction where every time a neutron hits a nucleus, the nucleus splits in two and sends out more neutrons.
What process takes place when uranium-235 splits into two smaller nuclei plus neutrons?
This process is called nuclear fission.
When an atom of uranium 235 is bombarded with neutrons it splits into smaller nuclei and produces a great amount of energy This nuclear process is called?
This nuclear process is called nuclear fission. During nuclear fission, the uranium-235 atom absorbs a neutron, becomes unstable, and splits into two smaller nuclei (fission fragments) and releases energy and more neutrons.
Do uranium nuclei split during nuclear fission?
if the fission was of uranium, then yes. but many transuranic elements (e.g. plutonium, americium) also fission.
What is the particle required to continue the chain process of Uranium fission?
A neutron is the particle required to continue the chain process of Uranium fission. When a Uranium-235 nucleus absorbs a neutron, it becomes unstable and splits into two smaller nuclei, releasing energy and additional neutrons that can then go on to induce further fission reactions in nearby nuclei.
What is the formula of uranium-235 during fission?

Where do The neutrons for nuclear fission come From in a nuclear chain reaction?
In a nuclear chain reaction, neutrons for nuclear fission primarily come from the fission of heavy atomic nuclei, such as uranium-235 or plutonium-239. When these nuclei absorb a neutron and become unstable, they split into smaller nuclei, releasing additional neutrons in the process. These emitted neutrons can then initiate further fission reactions in nearby nuclei, sustaining the chain reaction. Thus, the process relies on the self-propagating nature of neutron release and absorption.
Do protons hit uranium causing it to split?
Protons do not directly hit uranium to cause it to split. Uranium undergoes nuclear fission when bombarded by neutrons, not protons. The neutrons are absorbed by the uranium nucleus, leading to its splitting into smaller nuclei and the release of energy.
What is the process in which a heavy nucleus divides to form smaller nuclei one or two neutrons and a large amount of energy?
The process you are referring to is nuclear fission. In this process, a heavy nucleus such as uranium-235 is bombarded with a neutron, causing it to split into two smaller nuclei, along with the release of one or two additional neutrons and a significant amount of energy. This chain reaction is the basis for nuclear power plants and nuclear weapons.
When a uranium nucleus breaks into fragments what type of nuclear reaction occurs?
In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei), often producing free neutrons and photons (in the form of gamma rays).
What is produced when uranium nuclei is bombarded with neutrons?
This depends on a lot of things. When a neutron collides with an uranium atom, it might bounce off, cause the atom to decay, or be captured into the atom. But which it does depends on the isotope of the atom, the temperature of the atom, and the velocity of the neutron. My understanding is that it can cause any isotope of uranium to decay, and certainly it can bounce off any, but it can only be captured by U233, U234, or U235; the other isotopes of uranium, U236, and U238, will not capture neutrons. The interactions of various isotopes of different temperatures with neutrons of different velocities is complicated, and no simple rule about it can be stated.

What causes a chain reaction in uranium?
Each atom, when split, releases one or more neutrons. Those neutrons go on to destabilize and split other atoms. This is the "chain reaction" we talk about. The multiplication factor, known as Keffective represents the rate of increase in reactivity. If Keffective is 1, then, on average, one atom's split results in one neutron that splits one atom.
