Nuclear Chemistry - Result Question 12
12. The nuclear reactions accompanied with emission of neutron(s) are
(1988, 1 M)
(a) ${ } _{13}^{27} Al+{ } _2^{4} He \longrightarrow{ } _{15}^{30} P$
(b) ${ } _6^{12} C+{ } _1^{1} H \longrightarrow{ } _7^{13} N$
(c) ${ } _{15}^{30} P \longrightarrow{ } _{14}^{30} Si+{ } _1^{0} e$
(d) ${ } _{96}^{241} Cm+{ } _2^{4} He \longrightarrow{ } _{97}^{244} Bk+{ } _1^{0} e$
Show Answer
Answer:
Correct Answer: 12. (a, d)
Solution:
- If sum of mass number of product nuclides is less than the sum of parent nuclides, then neutron emission will occur. In both (a) and (d), sum of mass number of product nuclides is one unit less than the sum of parent nuclides, neutron emission will balance the mass number.
