Question:

The process that releases neutrons from the nucleus is

Show Hint

The release of neutrons in fission allows for a chain reaction, which is the basis for nuclear reactors and atomic bombs.

The Correct Option is

Solution and Explanation

Step 1: Understanding the Concept:
Different nuclear processes involve the emission of different particles.

Step 2:
Detailed Explanation:

• \(\alpha\)-decay: Emits an alpha particle (\(_2^4He\) nucleus).
• \(\beta\)-decay: Emits an electron (\(_{-1}^0e\)) or positron.
• Nuclear fusion: Two light nuclei combine to form a heavier nucleus, releasing energy, but not typically free neutrons as a primary product (though some fusion reactions like D+T produce neutrons).
• Pair production: A photon creates an electron-positron pair. No neutrons.
• Nuclear fission: A heavy nucleus (e.g., U-235) splits into two lighter nuclei, and typically 2-3 free neutrons are released. This is the process that releases neutrons from the nucleus.

Step 3:
Final Answer:
Nuclear fission releases neutrons.
