Question

Quizplus · Accepted Answer

This question requires knowledge of the concept of magic numbers in nuclear physics. Magic numbers are specific numbers of neutrons or protons that when present in a nucleus, make it more stable than neighboring nuclei. The magic numbers for both neutrons and protons are 2, 8, 20, 28, 50, 82, and 126.

Option B has 28 protons, which is a magic number, and 50 neutrons, which is also a magic number. Therefore, option B has both a magic number of neutrons and protons and is the best choice. None of the other options have magic numbers of either neutrons or protons.
