What contains a heavy atom often used in nuclear fission reactions to produce thermal energy?
Uranium-235 is a heavy atom commonly used in nuclear fission reactions to produce thermal energy. When a uranium-235 atom absorbs a neutron, it becomes unstable and splits into two smaller atoms along with releasing energy and additional neutrons, which can trigger a chain reaction.
What is needed to produce different isotopes during fission?
The fission reaction must be possible.
Is it true that the daughter products of nuclear explosions produce heavy but stable isotopes of uranium?
No, the daughter products of nuclear explosions do not produce stable isotopes of uranium. Instead, uranium isotopes can undergo fission or neutron capture to form various other radioactive isotopes as byproducts.
Which contains a heavy atom often used in nuclear fission reactions to produce thermal energy?
Uranium-235 is a heavy atom commonly used in nuclear fission reactions to produce thermal energy. When uranium-235 absorbs a neutron, it becomes unstable and splits into smaller nuclei, releasing a large amount of energy in the form of heat, which is then used to generate electricity in nuclear power plants.
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.
How does Thorium produce electricity?
Thorium can produce electricity through a process called nuclear fission. When thorium nuclei absorb a neutron, they can split, releasing energy in the form of heat. This heat is then used to generate steam, which drives a turbine connected to a generator to produce electricity.
For a fission reaction to fail to be maintained as a chain reaction each fission must produce less than additional fission reaction(s).?
In a continuous chain reaction at a steady rate, which gives a steady power output from a fission reactor, every fission gives rise to another fission. This happens because in every fission 2 or 3 neutrons are produced, some are absorbed or lost, but if just one is captured by another fissionable nucleus, the chain reaction will continue. Apex answer = 1
When a certain isotope such as U 238 is hit by a neutron it will always split into the same smaller nuclei?
No, not at all. Simple decay (alpha decay, beta decay, K capture, etc.) will always produce the same daughter products, but with neutron-induced fission it's ... well, it's not quiterandom, but it's certainly not going to always produce the same products.

The fission reaction must be possible.
What does the fission of U 235 produce?
Heat, fission products, neutrons, gamma rays
Does the process of fission produce radioactive waste?
Yes, the process of fission produces radioactive waste.
What property of the fission reaction leads to the possibility of a chain reaction?
The fact that when a fission occurs, more than one neutron is released. Thus by careful design, one of these second generation neutrons can be captured by a further nucleus causing another fission, and so on. Up to about 2.5 neutrons per fission can be utilized. In a bomb, all of them are used, and the reactivity (approximately) doubles with each reaction. In a controlled reaction, such as in a reactor, the moderator and geometry are such that one neutron per fission goes on to create another fission, yielding a stable reactivity.

No, the daughter products of nuclear explosions do not produce stable isotopes of uranium. Instead, uranium isotopes can undergo fission or neutron capture to form various other radioactive isotopes as byproducts.
What particle is needed to begin a nuclear chain reaction?
Neutrons are the important particles of nuclear chain reactions and the reactions depend on them. The neutrons do not really start the fission, reaction, however, because the neutrons come from fission in the fuel.The material in the fuel, typically a mix of 235U and 238U, undergoes fission spontaneously. When a fission event happens, more neutrons, typically two or three, are emitted. These bounce about from atom to atom, until they cause another atom to undergo fission, releasing more neutrons to increase the rate at which atoms undergo fission.But the neutrons needed for the chain reaction are actually produced by the fuel spontaneously, and these are produce in an ongoing manner with or without critical mass. So it is not a particle that starts the chain reaction; it is the act of putting together a critical mass.
What type of reactor uses fission to produce energy?
There are two primary design styles of fission reactors to produce electricity. Pressurized, and Boiling water reactors.
A nucleus captures two neutrons and decays to produce one neutron is this process likely to produce a chain reaction?
Yes, if the nucleus is undergoing fission and releasing additional neutrons upon decay, capturing two neutrons could contribute to a chain reaction by generating more fission events and more neutrons. However, the likelihood of a chain reaction occurring also depends on the specific nucleus involved and the surrounding conditions.
