What change occurs during nuclear fission?
Elements are created that differ from the reactants.
What are fission fragments?
When an atomic nucleus fissions, it splits into smaller atomic nuclei. These smaller atomic nuclei are referred to as "fission fragments." The unstable nucleus of a radioactive element can fission (split) into smaller nuclei, i.e. those of lighter elements. This can also release other atomic particles, as well as energy. In nuclear power and atomic weapons, the fission process is initiated to release the nuclear energy. Natural fission is a much rarer occurrence than radioactive decay.
What is it called when two nuclei fuse together?
Fusion. When a nucleus splits into two or more fragments this is called Fission.
Which nuclear reaction occurs when one nucleus splits into two nuclei?
Nuclear Fission
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)
Nuclear reaction in which an unstable atomic nucleus splits into two roughly equal parts?
Fission.
What change occurs during nuclear fission?
Elements are created that differ from the reactants.
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 are different types nuclear heat?
fission: nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller partsfusion: nuclear fusion is the process by which two or more atomic nuclei join together "fuse"
Are all fission events in a chain reaction identical?
Nuclear event in a chain reaction could be said to be similar, but not identical. We need to look a bit more closely at a fission event to understand why. In a fission event in a chain reaction, a neutron is absorbed by a fissile nucleus, and the resulting instability causes that nucleus to fission, or split. When the nucleus splits, it splits into two approximately parts (called fission fragments), but not the same two parts will appear in every fission event. And one, two or three neutrons might appear, depending on exactly which two fission fragments appear. The total energies in the events will vary from event to event as well, and this has something to do with the energy the absorbed neutron brings when it is absorbed. We know fission events are similar, but there are variations that preclude them being identical.
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.
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.
