The splitting of a heavy nucleus is called?
nuclear fission
What process takes place when uranium -235 splits into two smaller nuclei plus neutrons?
This is called nuclear fission. During this process a small amount of mass is annihilated which produces energy
Spliting of nucleus into smaller fragments?
the splitting of the nucleus into smaller fragments is called fission.This was the same process used when the US dropped its atomic bombs on Hiroshima and Nagasaki during WWII back in 1945 using Uranium in one, and Plutonium in the other.
What term is use to describe splitting a large atomic nucleus into smaller ones?
Nuclear fission is defined as splitting large nuclei into smaller ones.
Does Uranium 238 and 235 release neutrons in nature as they do in a fission process?
Yes, by spontaneous fission, but the nymber of neutrons is very small because the halflife of the spontenuoes fission is: for Uranium 235: (1,0 ± 0,3).1019 years for Uranium 238: (8,20 ± 0,10).1015years
What is true about the fission of uranium235?
The reaction produces more neutrons than were needed to start it.
What is the form of nuclear energy?
Nuclear energy as used in power plants results from fission of uranium235 and plutonium239
What is the only thing that can get changed in a balancing equation?
It is the mass defect during a fission reaction. Enrgy evolved during a radioactive fission can be calculated using the formula gived by Einstein e =mc
Comparison of fission fusion and transmutation?
Fission is the splitting of heavy nuclei, mostly Uranium235 but also Plutonium 239, which is made to happen in nuclear fission reactors, and releases energy. Transmutation of elements occurs in this process as when the heavy nucleus splits, two lighter nuclei of other elements such as caesium, strontium, iodine, are formed, these are the fission products. Fusion is the joining together of two nuclei, the ones being experimented with being deuterium and tritium, both isotopes of hydrogen. These transmute to helium during fusion.
Atomic energy is the energy of heat mass or fluorescence?
Atomic energy is produced when atoms of uranium235 or other fissile material split, or undergo fission. It is nothing to do with fluorescence, and I don't understand 'heat mass'
Is energy released during fission but absorbed during fusion?
Energy is released during fusion and fission.
A uranium235 sample starts with 200 atoms and 700 million years later there are 100 atoms What is the halflife of uranium235?
700 milliion years. The definition of half-life is the period of time during which one-half of the atoms of an element undergo decay into other elements.
What is fission product?
Fission products are the fragments resulting from the fission of heavy nuclids during nuclear fission process
Is Potential Energy released during fission?
Yes. Uranium contains potential energy, and the energy is released during fission.
Which describes what happens during a chain reaction?
Neutrons released during a fission reaction trigger other fission reactions.
How do neutrons electrons and protons relate to nuclear energy?
These are the constituents of atoms. Nuclei are made up of protons and neutrons. Useful nuclear energy is only obtained from a few nuclei which can be made to fission and release energy. The two main ones are Uranium235 and Plutonium239.
What is needed to produce different isotopes during fission?
The fission reaction must be possible.
