Answer 1

The least stable nucleus is Fe.

Option (D) is correct.

Explanation:

The least stable nucleus is Fe.

• Nuclear stability means that the nucleus of an element is constant and it does not spontaneously produce radiations.
• The nuclei with the maximum binding energy are the most stable e.g Carbon.
• A stable atom has enough binding energy to hold the nucleus together permanently.
• An unstable atom does not have enough binding energy to hold the nucleus together permanently and is called a radioactive atom.
