Question

3. In nuclear fission, every 2U gives
... neutrons.​

Answer 1

Answer:

Nuclear fission is a process where the nucleus of an atom is split into two or more smaller nuclei, known as fission products.

The fission of heavy elements is an exothermic reaction, and huge amounts of energy are released in the process.

Nuclear fission occurs with heavier elements, where the electromagnetic force pushing the nucleus apart dominates the strong nuclear force holding it together.

In order to initiate most fission reactions, an atom is bombarded by a neutron to produce an unstable isotope, which undergoes fission.

When neutrons are released during the fission process, they can initiate a chain reaction of continuous fission which sustains itself.

Key Terms

fissile: Capable of undergoing nuclear fission.

nucleon: One of the subatomic particles of the atomic nucleus, i.e. a proton or a neutron.

nuclear fission: Radioactive decay process in which the nucleus of an atom splits into lighter nuclei.
