Question

Which of the following nuclei would likely be the least stable

A) A nucleus with two protons and two neutrons

B) A nucleus with eight protons and eight neutrons

C) A nucleus with 17 protons and 17 neutrons

D) A nucleus with 28 Protons and 28 neutrons

Answer 1

pretty sure the answer is c but not completely positive !

Answer 2

Answer: option C

Explanation: since as we know that if no of protons or no of neutrons are equal to Magic numbers(2,8,20,28,50,82,126) then that nuclei are exceptionally stable.

Here in our case, except Option C , all have magic no of protons and neutrons. Hence Option C is least stable. Since C is not a magic number
