The nucleus splits to form two or more smaller nuclei.
What else can I help you with?
Is fission a particle?
Fission is not a particle. It is a nuclear reaction in which the nucleus of an atom splits into two or more smaller nuclei, along with the release of a large amount of energy and usually some neutrons.
Which particle is commonly used to initiate a fission chain reaction?
Neutrons are commonly used to initiate a fission chain reaction. When a neutron collides with a nucleus of a fissile material like uranium-235 or plutonium-239, it can split the nucleus, releasing more neutrons and causing a chain reaction.
What is the bullet that starts a fission reaction?
The bullet that starts a fission reaction is a neutron. When a neutron collides with the nucleus of a fissile isotope, such as uranium-235, it can induce the nucleus to undergo fission, releasing more neutrons and a large amount of energy.
What always splits when fission is around?
The nucleus of an atom always splits when fission occurs. Fission is a nuclear reaction in which the nucleus of an atom splits into two or more smaller nuclei.
A nuclear reaction in which an atoms nucleus is split into two smaller nuclei and energy is released as heat is known as?
nuclear fission
Is fission a particle?
Fission is not a particle. It is a nuclear reaction in which the nucleus of an atom splits into two or more smaller nuclei, along with the release of a large amount of energy and usually some neutrons.
What is the definition for nuclear fission?
A nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy.
What particle is nessicary to start a fisson reation?
Neutrons are necessary to start a fission reaction. When a neutron collides with a heavy atomic nucleus, such as uranium-235, it can induce the nucleus to split and release more neutrons, leading to a chain reaction.

Neutrons are commonly used to initiate a fission chain reaction. When a neutron collides with a nucleus of a fissile material like uranium-235 or plutonium-239, it can split the nucleus, releasing more neutrons and causing a chain reaction.
What is induced nuclear fission?
We might think of induced nuclear fission as a fission reaction that occurs when a neutron is captured by, say, a uranium-235 atom and that atomic nucleus undergoes fission as a result. Most all of the fission events within a nuclear reactor or nuclear weapon are induced. Given this, we might then compare that fission event to a spontaneous fission event wherein the atomic nucleus of a uranium-235 atom spontaneously undergoes fission without having captured a neutron.
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 atom’s nucleus. (apex)
Whats the nuclear reaction of fission?
The splitting of a nucleus atom
What is the bullet that starts a fission reaction?
The bullet that starts a fission reaction is a neutron. When a neutron collides with the nucleus of a fissile isotope, such as uranium-235, it can induce the nucleus to undergo fission, releasing more neutrons and a large amount of energy.
Why thermal neutron has greater chance to induce fission?
The thermal neutron is possibly the most energetic and powerful form of radiation. Apart from extensive alpha particle bombardment in certain fissile nuclides, neutrons are the only particle which effectively sustains a chain fission reaction.
What always splits when fission is around?
The nucleus of an atom always splits when fission occurs. Fission is a nuclear reaction in which the nucleus of an atom splits into two or more smaller nuclei.
What is fission in physics?
In physics, fission is the process in which a heavy, unstable element is split into two lighter elements by bombarding it with a small particle. Some of the energy that was binding the element's nucleus together is then released, along with a third, tiny particle that is released as well. The tiny particle then collides with another of the heavy elements, causing it to split as well, emitting another particle which collides with another heavy element, and so on. This is the chain reaction that allows for sustainable nuclear power generation, in which the reaction is controlled, or the detonation of nuclear weapons, in which the reaction is uncontrolled.
When a nucleus undergoes radioactive decay its new mass number is?
It depends. If the decay contains a particle with mass, then the nucleus' mass number must decrease. If the decay involves the emission of a massless particle (like a gamma photon), then the mass number is unchanged. If the reaction (not technically a decay) involves the nucleus absorbing a particle with mass (like U-235 absorbing a neutron in a fission chain reaction) then it is a transmutation and not a natural decay. The mass number must increase.
