Answer 2

Individual pairs of proton and neutrons have opposed spin and consequently, the spin of the nucleus as a whole is 0. (Option A)

• The number of protons and neutrons can be used to compute nuclear spin.
• It is determined by the distribution of unpaired protons in energy levels.
• The net spin is zero if indeed the number of nucleons is equal, and 1/2, 3/2 if the proton count is odd (unpaired proton present).
• The total spin of the nuclei will be determined by the unpaired nucleon.
• Nuclear spin equals the sum of spin and orbital motion.
• In this question, it is given that the number of protons and neutrons is equal. Consequently, the spin will be canceled out to be zero.
• Thus, individual pairs of proton and neutrons have opposed spin and consequently, the spin of the nucleus as a whole is 0.
• Option A is the answer.
