Question

Which best describes what forms in nuclear fission?
A:two smaller, more stable nuclei
B:two larger, less stable nuclei
C:one smaller, less stable nucleus
D:one larger, more stable nucleus

Answer 1

Answer:

The correct option is A) two smaller, more stable nuclei.

Explanation:

• The splitting of a heavy nucleus, such as uranium or plutonium, into two smaller nuclei with almost the same mass, is known as nuclear fission.
• The unstable radioactive nucleus splits into two stable nuclei, known as fission products, during this process.
• As a result of their increased stability, the fission products are more difficult to separate.
• Nuclear fission can sometimes happen on its own or can be caused by bombarding the nucleus with various particles, such as protons, neutrons, or alpha particles, or by exposure to gamma rays.
• A significant amount of energy is produced during this fission process, leading to the creation of more radioactive elements as well as the release of numerous neutrons.
• These neutrons can also trigger a chain fission process in the uranium or plutonium nucleus, which would then release further neutrons.
• This may cause an uncontrollable chain reaction that continues until all the initial material has been used up and a significant amount of energy is also produced.
