Which types of particles are involved in a fission reaction?
A neutral neutron strikes a large neutral nucleus.
A positive proton strikes a large positive nucleus.
A neutral neutron strikes a large positive nucleus.
A positive proton strikes a large neutral nucleus.
The type of particle involved in a fission reaction is a neutral neutron striking a large positive nucleus.
The correct answer is: A neutral neutron strikes a large positive nucleus.
Explanation: In a fission reaction, a process where the nucleus of an atom splits into two smaller nuclei, it is primarily neutrons that induce this reaction. When a neutral neutron (no charge) collides with a large positive (charged) nucleus, such as uranium-235 or plutonium-239, it can cause the nucleus to become unstable, leading to its fragmentation and the release of additional neutrons. These released neutrons can then go on to collide with other nuclei, leading to a chain reaction and the release of a significant amount of energy. The other options provided do not accurately describe the particles involved in a fission reaction.
NEUTRons are NEUTRal
nuclei are positive (protons and neutrons)
nuclei fission thru neutron capture
