When the U-235 nucleus absorbs a thermal neutron BA 141 and KR 92 nuclei are produced along with some neutrons how many neutrons are emitted?
three
The original uranium-235 nucleus absorbs a neutron, splits into a krypton-92 nucleus and a barium-141 nucleus, and releases three more neutrons upon splitting. Those three neutrons are then able to cause the fission of three more uranium-235 nuclei, each of which release more neutrons, and so on.
When uranium-235 has a fission reaction it releases a chain reaction?
neutrons
The neutrons released when uranium-235 fissions may crash into other uranium nuclei and cause them to fission as well. This can start a nuclear chain reaction. You can see how this happens in the Figure below. In a chain reaction, one fission reaction leads to others, which lead to others, and so on.
What is the fission equation for uranium-235?
Most fission produces neutrons, although the number varies with each fission. This is an extremely important aspect of fission, because neutrons can induce more fission, enabling self-sustaining chain reactions. n+23592U→14256Ba+9136Kr+3n n + 92 235 U → 56 142 Ba + 36 91 Kr + 3 n .
When bombarded by a neutron uranium-235 undergoes fission of the nuclides produced are barium 141 and krypton 92 how many neutrons are emitted?
Why does induced fission of uranium-235 cause a chain reaction?
A possible nuclear fission chain reaction. A uranium-235 atom absorbs a neutron, and fissions into two (fission fragments), releasing three new neutrons and a large amount of binding energy. 2. One of those neutrons is absorbed by an atom of uranium-238, and does not continue the reaction.
Why can U-235 produce a chain reaction quizlet?
Why can U-235 produce a chain reaction? Neutrons produce the fission reaction and are also a product of the reaction.
How much energy is released when one uranium-235 nucleus undergoes fission?
The total binding energy released in fission of an atomic nucleus varies with the precise break up, but averages about 200 MeV* for U-235 or 3.2 x 10-11 joule. This is about 82 TJ/kg.
