This is called nuclear fission. During this process a small amount of mass is annihilated which produces energy

When a neutron in absorbed by a U-235 nucleus what is the neutron number?
The atomic number of uranium is 92, so its atoms have 92 protons in their nuclei. If uranium-235 absorbs a neutron, it would then have the mass number of 236. The number of neutrons is the mass number minus the atomic number, so the number of neutrons in the uranium-236 nuclei would be 236-92=144.
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).
Do you burn uranium to power nuclear energy?
It is not burning in the normal chemical sense, though nuclear engineers do talk about fuel burnup. By this they mean the amount of energy extracted from a tonne of fuel. The process is nuclear fission which means that the uranium nuclei split apart into two smaller fragments, and this releases thermal energy.
Why is a larger nucleus not as stable as a smaller nucleus?
A smaller nucleus is generally more stable. Below are some general rules: # (Except for really small nuclei) All stable nuclei contain a number of neutrons that is equal to or greater than the number of protons. # Nuclei with too few or too many neutrons is unstable. # If a nuclei has even numbers of nucleons, it's generally more stable. # Nuclei with "magic numbers" usually tend to be more stable.
How can uranium 235 create electricity?
In physics and nuclear fission. A neutron is fired at a uranium-235 atom which then splits into daughter nuclei, the daughter nuclei releases more netrons which splits more and more uranium-235 atoms. This is called a chain reaction. The chain reaction releases heat which can then be used to turn a turbine which turns a generator and generates electricity. A moderator can be used to slow down neutrons and the chain reaction. When the neutrons are slowed down to the right speed, control/fuel rods absorbs the neutrons which slows down the reaction rate. This makes nuclear fission controllable, unlike nuclear fusion which is uncontrollable. Hope this helps
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?
Nuclear fission
Uranium-235 is bombarded with neutrons and splits into smaller nuclei and produces a great amount of energy?
Yes
What nuclear process is happening during the main sequence?
Nuclear fission. It realeases nuclear energy by spitting big atomic nuclei, usually those of uranium. Neutrons are fired at the nuclei. As the neutrons smash into the nuclei they split off more neutrons, which bombard other nuclei, setting of a chain reaction, which makes 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?
radioactive decay
Can a nuclear reaction naturally stop?
Yes. How quickly depends on available material. In a nuclear reactor, neutrons bombard uranium atoms, destabilising the nucleus. The unstable nucleus splits into two smaller nuclei. Smaller nuclei contain proportionally less neutrons and the spare neutrons are ejected. These are available for further bombardment, but usually require slowing down (moderating) before a good chance of a chain reaction occurs. For a chain reaction there needs to be sufficient fissile material (the uranium) and sufficient thermal (quite slow) neutrons. A lack of these will lead to the chain reaction coming to a halt.
Why are neutrons fired at the uranium nuclei?
Under bombardment with thermal neutrons a nuclear fission is produced with the isotopes 235U and 233U; a formidable energy is released after fission.
When a neutron in absorbed by a U-235 nucleus what is the neutron number?
The atomic number of uranium is 92, so its atoms have 92 protons in their nuclei. If uranium-235 absorbs a neutron, it would then have the mass number of 236. The number of neutrons is the mass number minus the atomic number, so the number of neutrons in the uranium-236 nuclei would be 236-92=144.
Uranium 235 and uranium 238 are isotope are chemically different why?
An isotope means an atom with the same amount of electrons and protons, but with different amount of neutrons.Relative weight of a neutron is 1, a proton is 1, and an electron is very small. So weight of an atom is approx. mneutrons + m protons.So, an uranium-235, as U is the 92th atom in periodic table, contains 92 protons, 92 electrons to be chargeless, and 143 (=235-92) neutrons.An uranium-238, from the definition of isotope, contains 92 protons, 92 electrons, and 146 (=238-92) neutrons.The difference is the 3 neutrons.
When uranium 235 is struck with a neutron the krypton 92 and barium 141 nuclei are produced along with some neutrons how many neutrons are produced?
The average number of neutrons per nuclear fission is 2,5.
Why do they happen nuclear explosion?
Nuclear explosions happen for many reasons: An uncontrolled chain reaction (fission reaction) occurs with uranium 238, A fission reaction is where 1 large nucleus (centre of an atom) splits up into 2 or more smaller nuclei giving off neutrons. These neutrons then hit another nucleus changing it into smaller nuclei and so on. e.g. (chain reaction) feel free to add some more info...
What is fision?
fission- is a process in which the nuclei of radioactive atoms are split in to two or more smaller nuclei.
